The function mmc_offset_try_partition searches MMC partition to save the
environment data by name. However, it only compares the first word-size
bytes (size of 'const char *'), which may make the function to find
unintended partition.
Correct the function not to partially compare the partition name with
config "u-boot,,mmc-env-partition".
