nfp: fix incorrect use of mbox in IPsec code

Browse source

The mailbox configuration mechanism requires writing several registers,
which shouldn't be interrupted, so need lock to avoid race condition.

The base offset of mailbox configuration registers is not fixed, it
depends on TLV caps read from application firmware.
