ext4: ignore quota mount options if the quota feature is enabled
Previously, ext4 would fail the mount if the file system had the quota feature enabled and quota mount options (used for the older quota setups) were present. This broke xfstests, since xfs silently ignores the usrquote and grpquota mount options if they are specified. This commit changes things so that we are consistent with xfs; having the mount options specified is harmless, so no sense break users by forbidding them.
