    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.
