  firmware: arm_ffa: Skip Rx buffer ownership release if not acquired (2025-04-08 10:32:15 +0100)

----------------------------------------------------------------
Arm FF-A fix for v6.15

A fix that addresses incorrect release of Rx buffer ownership in the
driver. The fix specificially avoids releasing Rx buffer ownership with
FFA_RX_RELEASE if it wasn’t acquired during a FFA_PARTITION_INFO_GET call
that only requested the partition count. This prevents unnecessary errors
like FFA_RET_DENIED from firmware when buffers are not actually owned by
the driver.
