[SCSI] sym53c8xx: Fix bogus sym_que_entry re-implementation of container_of
The sym53c8xx driver, for some reason, seems to mostly re-implement linux/list.h with added bogosity. The main one is it's implementation of sym_que_entry which spits warnings with recent gcc's on some 64 bits architectures.
