SCSI: sd: Fix parsing of 'temporary ' cache mode prefix
commit 2ee3e26c673e75c05ef8b914f54fadee3d7b9c88 upstream.
Commit 39c60a0948cc '[SCSI] sd: fix array cache flushing bug causing
performance problems' added temp as a pointer to "temporary " and used
sizeof(temp) - 1 as its length. But sizeof(temp) is the size of the
pointer, not the size of the string constant. Change temp to a static
array so that sizeof() does what was intended.
