Make sure to use the current alternate setting when verifying the
interface descriptors to avoid binding to an invalid interface.
Failing to do so could cause the driver to misbehave or trigger a WARN()
in usb_submit_urb() that kernels with panic_on_warn set would choke on.

In order to make the entire kernel usable under Clang's Control Flow
Integrity protections, function prototype casts need to be avoided
because this will trip CFI checks at runtime (i.e. a mismatch between
the caller's expected function prototype and the destination function's
prototype). Many of these cases can be found with -Wcast-function-type,
which found that the rtl wifi drivers had a bunch of needless function
casts. Remove function casts for tasklet callbacks in the various drivers.

The `rtl8188eu` driver is built as a kmod in order to avoid symbol
conflicts (at link-time) with other Realtek drivers.
Internally, we use this driver as builtin [vs kmod], and we've identified
the `efuse_power_switch()` symbol to be conflicting at link-time with the
one from the `rtlwifi` driver.
An alternative solution would have been to rename the function, but it
doesn't look like it's being used outside of this driver, so just make it
static.

If kzalloc() returns NULL, the error path doesn't stop the flow of
control from entering rtw_hal_read_chip_version() which dereferences the
null pointer. Fix this by adding a 'goto' to the error path to more
gracefully handle the issue and avoid proceeding with initialization
steps that we're no longer prepared to handle.
Also update the debug message to be more consistent with the other debug
messages in this function.

Inside a nested 'else' block at the beginning of this function is a
call that assigns 'psta' to the return value of 'rtw_get_stainfo()'.
If 'rtw_get_stainfo()' returns NULL and the flow of control reaches
the 'else if' where 'psta' is dereferenced, then we will dereference
a NULL pointer.
Fix this by checking if 'psta' is not NULL before reading its
'psta->qos_option' data member.
