[SCSI] advansys: Remove some custom wrappers
- Replace ASC_ASSERT() with BUG_ON(). In a few places, get rid of the assertion altogether -- the ensuing crash will tell us all we need to know. Use BUG() where it fits better than BUG_ON(). Also fix a fencepost error in advansys_proc_info(). - Replace DvcSleepMilliSecond with mdelay. Despite its name using 'sleep', the implementation was a delay. I've marked some places with XXX where we should probably be using msleep instead. They need to be audited to be sure we can sleep in that context. - Replace DvcDelayMicroSecond with udelay. - Replace DvcDelayNanoSecond with udelay too. All callers were multiples of 1000. - Remove DvcEnterCritical and DvcLeaveCritical. These functions are no-ops, and as the comments said, the spinlock protects the critical sections.
