When running the "save" command several times on a mx6qsabresd we see:
U-Boot > save
Saving Environment to MMC...
Writing to MMC(1)... done
U-Boot > save
Saving Environment to MMC...
MMC partition switch failed
U-Boot > save
Saving Environment to MMC...
Writing to MMC(1)... done
U-Boot > save

MMC partition switch failed
U-Boot > save
Saving Environment to MMC...
Writing to MMC(1)... done
U-Boot > save

MMC partition switch failed
Fix this by making mmc->part_num to be in sync with CONFIG_SYS_MMC_ENV_PART
after the partition has been changed in mmc_switch_part().
After this fix, we no longer see the error after the "save" command on a
mx6qsabresd. Also tested on a mx53loco.
