scsi: sg: reset 'res_in_use' after unlinking reserved array
commit e791ce27c3f6a1d3c746fd6a8f8e36c9540ec6f9 upstream.
Once the reserved page array is unused we can reset the 'res_in_use'
state; here we can do a lazy update without holding the mutex as we only
need to check against concurrent access, not concurrent release.
[mkp: checkpatch]
