[XFS] fix mount option parsing in remount
Remount currently happily accept any option thrown at it, although the only filesystem specific option it actually handles is barrier/nobarrier. And it actually doesn't handle these correctly either because it only uses the value it parsed when we're doing a ro->rw transition. In addition to that there's also a bad bug in xfs_parseargs which doesn't touch the actual option in the mount point except for a single one, XFS_MOUNT_SMALL_INUMS and thus forced any filesystem that's every remounted in some way to not support 64bit inodes with no way to recover unless unmounted. This patch changes xfs_fs_remount to use it's own linux/parser.h based options parse instead of xfs_parseargs and reject all options except for barrier/nobarrier and to the right thing in general. Eventually I'd like to have a single big option table used for mount aswell but that can wait for a while.
