In __ext4_fill_super(), s_resgid is initialized by calling
ext4_get_resuid() instead of ext4_get_resgid(), resulting in the
reserved GID being set to the same value as the reserved UID rather
than the value stored in the superblock.
Fixes: 12c84dd4d308 ("ext4: add support for 32-bit default reserved uid and gid values")
