Linux 4.2 compat: remove bio->bi_cnt access

Browse Source 
Linux 4.2 commit torvalds/linux@dac5621 renamed bio->bi_cnt to
bio->__bi_cnt.  Because this value is only used once in a block of
debug code it simplest just to remove the PANIC.  To my knowledge
this debugging has never been hit or proved useful so this is no
great loss.
