wifi: orinoco: check return value of hermes_write_wordrec()

There is currently no return check for writing an authentication
type (HERMES_AUTH_SHARED_KEY or HERMES_AUTH_OPEN). It looks like
it was accidentally skipped.

This patch adds a return check similar to the other checks in
__orinoco_hw_setup_enc() for hermes_write_wordrec().

Detected using the static analysis tool - Svace.
