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