Subject: [PATCH 05/33] common/rc: streamline _scratch_remount

From: Darrick J. Wong <djwong@...nel.org>

Remounting a filesystem should be pretty straightforward invocation of
mount -o remount,XXX.  Instead, we go through _try_scratch_mount, which
recomputes the filesystem type and the mount options, which is probably
not what the caller actually wanted.  Streamline this by calling the
_mount wrapper directly.

This also means that /sbin/mount.$FSTYP won't be invoked for a remount,
which doesn't work if that binary is actually a fuse filesystem driver.
