remove useless mnt_want_write call in xfs_write
When mnt_want_write was introduced a call to it was added around
xfs_ichgtime, but there is no need for this because a file can't be open
read/write on a r/o mount, and a mount can't degrade r/o while we still
have files open for writing. As the mnt_want_write changes were never
merged into the CVS tree this patch is for mainline only.
