io_uring/rw: drop unused attr_type_mask from io_prep_rw_pi()

Browse Source 
io_prep_rw_pi() never used the attr_type_mask argument. Callers already
validate sqe->attr_type_mask before invoking the helper (only
IORING_RW_ATTR_FLAG_PI is supported today). Remove the dead parameter to
avoid implying further interpretation happens here.
