PEL: Decrease the PLDM send failure retry time

The original desire for waiting 6s before retrying on a PLDM send failure
was in the hopes that the PLDM daemon would free up PLDM instance IDs
after that time in case they were all taken.

However, the PLDM daemon did not end up implementing that feature, and
even if it did now that the D-Bus call to get that is asynchronous the
send function would succeed in that case anyway.
