Subject: [PATCH RESEND] qla2xxx: Fix  START_SP_W_RETRIES checks _rval with positive
 EAGAIN

The START_SP_W_RETRIES macro incorrectly checked _rval with a positive
EAGAIN, despite qla2x00_start_sp consistently returning -EAGAIN for
retriable conditions. This mismatch could cause improper looping
behavior, failing to retry as intended and potentially leading to
unintended results in the system.

This patch fixes the macro to handle EAGAIN as -EAGAIN, ensuring
consistent error handling.
This change prevents any potential misinterpretation that could
introduce unexpected behavior.
