SELECT_DRIVE() is called by IDE core code in start_request() before device
driver's ->do_request method. In ide-scsi case ->do_request is implemented
by idescsi_do_request() which is also the only user of idescsi_issue_pc().

This flag was never being set in the code so remove it. By the way, the
code in the second patch was being executed unconditionally, i.e. in case
pc->retries > IDEFLOPPY_MAX_PC_RETRIES is true (actually that is the only case
when the outer if-test passed), !test_bit(PC_ABORT, &pc->flags)
was always true so the comment is now incorrect and has to go.
