Modified Files:
        src/sys/dev: fss.c fssvar.h

Log Message:
Add two new states FSS_CREATING and FSS_DESTROYING and use them
while creating or destroying a snapshot.

Remove now unneeded sc_lock that made fss_ioctl mutually exclusive.

Fss_ioctl no longer blocks forever because a snapshot gets
created or destroyed.

Serialize snapshot creation and make it interruptible.
