From: Eric Biggers <ebiggers@xxxxxxxxxx>
Since commit f2b4fa19647e ("ext4: switch to using the crc32c library"),
ext4_has_metadata_csum() is just an alias for
ext4_has_feature_metadata_csum(). ext4_has_feature_metadata_csum() is
generated by EXT4_FEATURE_RO_COMPAT_FUNCS and uses the regular naming
convention for checking a single ext4 feature. Therefore, remove
ext4_has_metadata_csum() and update all its callers to use
ext4_has_feature_metadata_csum() directly.
