IB/srpt: Post receive work requests after qp transition to INIT state
IB and iWARP specs both spell out that posting a receive work request
to a queue pair in the RESET state is an invalid operation and required
to fail. Postpone posting receive work requests until after the
transition to the INIT state.
Fixes: commit dea262094cdf ("IB/srpt: Change default behavior from using SRQ to using RC")
