[PATCH v3 05/11] IB/srp: Remove stale connection retry mechanism

[Bart Van Assche <bvanassche@acm.org>]

Attempting to connect three times may be insufficient after an
initiator system tries to relogin, especially if the relogin
attempt occurs before the SRP target service ID has been
registered. Since the srp_daemon retries a failed login attempt
anyway, remove the stale connection retry mechanism.
