bnxt_re/lib: Fix incorrect transfer length in bnxt_re_post_send

library is incorrectly setting transfer length/qkey_len in
bnxt_re_post_send handler if chain of Work Request is posted by
application. It doesn't update length when wr->num_sge is zero
and hence qkey_len is updated with stale data from length variable.

Initialize the bytes variable to zero in the loop.
