scsi: aha152x: Call scsi_done() directly

Conditional statements are faster than indirect calls. Hence call
scsi_done() and reset_done() directly. The changes in this patch are as
follows:

 - Remove the 'done' argument from aha152x_internal_queue().

 - Change ptr->scsi_done(ptr) into aha152x_scsi_done(ptr).

 - Inside aha152x_scsi_done(), check the 'resetting' flag of SCp.phase
   since aha152x_internal_queue() specifies the 'reset_done' function
   pointer if and only if the third argument has the value 'resetting'.
