pblk: fix max_io calculation
When calculating the maximun I/O size allowed into the buffer, consider
the write size (ws_opt) used by the write thread in order to cover the
case in which, due to flushes, the mem and subm pointers are disaligned
by (ws_opt - 1). This case currently translates into a stall when
an I/O of the largest possible size is submitted.
Fixes: f9f9d1ae2c66 ("lightnvm: pblk: prevent stall due to wb threshold")
