Ed Maste 0dcde5cc12 growfs: allow operation on RW-mounted filesystems
growfs supports growing mounted filesystems (writes are temporarily
suspended while the grow happens).  Drop the check for fs_clean == 0
to restore this case.  Leave fs_flags check for FS_UNCLEAN or
FS_NEEDSFSCK which represent the state of the filesystem when it was
mounted, and fsck should be run first if they are set.
