mmc: core: Re-work the code for eMMC sanitize
The error path for sanitize operations that completes with -ETIMEDOUT, is
tightly coupled with the internal request handling code of the core. More
precisely, mmc_wait_for_req_done() checks for specific sanitize errors.
This is not only inefficient as it affects all types of requests, but also
hackish.
Therefore, let's improve the behaviour by moving the error path out of the
mmc core. To do that, retuning needs to be held while running the sanitize
operation.
Moreover, to avoid exporting unnecessary symbols to the mmc block module,
let's move the code into the mmc_ops.c file. While updating the actual
code, let's also take the opportunity to clean up some of the mess around
it.
