remoteproc: qcom_q6v5_mss: map/unmap metadata region before/after use
The application processor accessing the dynamically assigned metadata
region after assigning it to the remote Q6 would lead to an XPU violation.
Fix this by un-mapping the metadata region post firmware header copy. The
metadata region is freed only after the modem Q6 is done with fw header
authentication.
