firmware: arm_ffa: Unmap Rx/Tx buffers on init failure

Browse source

[ Upstream commit 9fda364cb7 ]

ffa_init() maps the Rx/Tx buffers via ffa_rxtx_map() but on the
partition setup failure path it never unmaps them.

Add the missing ffa_rxtx_unmap() call in the error path so that
the Rx/Tx buffers are properly released before freeing the backing
pages.
