firmware: arm_ffa: Keep framework RX release under lock
The framework notification handler drops rx_lock before issuing
FFA_RX_RELEASE, leaving a window where another RX-buffer user can
start a new FF-A transaction before ownership has actually been
returned to firmware.
Move the FFA_RX_RELEASE calls so they execute while rx_lock is still
held on both the kmemdup() failure path and the normal success path.
While doing that, switch the handler to scoped_guard() to keep the
critical section explicit.
