scsi: core: Unexport scsi_track_queue_full()

Commit 408dea0 ("[PATCH] kill scsi_syms.c") exported
scsi_track_queue_full() and introduced a call to that function in
drivers/scsi/tmscsim.c. Commit 71bd849 ("tmscsim: replace by am53c974
driver") removed source file drivers/scsi/tmscsim.c. Since
scsi_track_queue_full() is no longer used outside the SCSI core, unexport
this function.
