Konstantin Belousov f99cb34c4f The process_deferred_inactive() function locks the vnodes of the ufs ...

mount, which means that is must not be called while the snaplock is
owned.  The vfs_write_resume(9) does call the function as the
VFS_SUSP_CLEAN() method, which is too early and falls into the region
still protected by snaplock.

Add yet another flag for the vfs_write_resume_flags() to avoid calling
suspension cleanup handler after the suspend is lifted, and use it in
the ffs_snapshot() call to vfs_write_resume.
