scripts/gdb: fix parameter handling in $lx_per_cpu
Before, the script tried to get the address by constructing a pointer to
the parameter (by name). However, since GDB now passes the parameter as a
GdbValue, we cannot get its name. Instead, we retrieve the address
through GdbValue's address attribute.
Before:
>>> p $lx_per_cpu(cpu_info)
Traceback (most recent call last):
File "./scripts/gdb/linux/cpus.py", line 152, in invoke
var_ptr = gdb.parse_and_eval("&" + var_name.string())
^^^^^^^^^^^^^^^^^
gdb.error: Trying to read string with inappropriate type `struct cpuinfo_x86'.
