LU-10321 lfsck: not start lfsck during umount

There is race condition bewtween lfsck_start and umount:
the LFSCK may be triggered just after the LFSCK stopped
during umount the target, then nobody will stop the new
started LFSCK, as to the umount may be blocked.

This patch sets flag on the lfsck instance when umount
that will prevent subsequent lfsck_start.
