Subject: [PATCH] rt2800usb: use rt2x00usb_register_multiwrite() to set key entries

Since struct hw_key_entry is 32-bytes large and is smaller than
CSR cache size (which is 64-bytes large) we can use the standard
rt2x00usb_register_multiwrite() helper to set key entries.

This cleanup is a part of preparations for later code unification.
