misc: rtsx: add missing write register handling

If an error occurs at the stage of working with registers in conjunction
with MCU_Block, it will not be processed.

The occurrence of errors at this stage may signal an impact on writes to
the device's PCI registers and is a more global problem than a
driver-level security problem, but adding a handler would be a good
practice.

Add a missing error handling.
