block: remove unused BLK_QC_T_EAGAIN flag

lostjeffle · axboe · commit 3aab91774bbd · 2020-09-25T07:54:50.000-06:00
commit 7b6620d ("block: remove REQ_NOWAIT_INLINE") removed the REQ_NOWAIT_INLINE related code, but the diff wasn't applied to blk_types.h somehow. Then commit 2771cef ("block: remove the REQ_NOWAIT_INLINE flag") removed the REQ_NOWAIT_INLINE flag while the BLK_QC_T_EAGAIN flag still remains.
