[PATCH] r/o bind mounts: drop write during emergency remount
The emergency remount code forcibly removes FMODE_WRITE from
filps. The r/o bind mount code notices that this was done
without a proper mnt_drop_write() and properly gives a
warning.
This patch does a mnt_drop_write() to keep everything
balanced.
