mmc: rtsx_pci_sdmmc: Remove set but unused variable 'err'
Seeing as sd_wait_data_idle() returns void and only a very specific
read value is checked, there doesn't seem to be a good reason to
check the return value of rtsx_pci_read_register(). So remove
the assignment and definition of 'err'.
Squashes the following W=1 kernel build warning:
drivers/mmc/host/rtsx_pci_sdmmc.c: In function ‘sd_wait_data_idle’:
drivers/mmc/host/rtsx_pci_sdmmc.c:678:6: warning: variable ‘err’ set but not used [-Wunused-but-set-variable]
678 | int err, i;
