UPSTREAM: firmware: arm_ffa: Fix uuid parameter to ffa_partition_probe

Browse Source 
While we pass uuid_null intentionally to ffa_partition_probe in
ffa_setup_partitions to get the count of the partitions, it must not be
uuid_null in ffa_partition_info_get which is used by the ffa_drivers
to fetch the specific partition info passing the UUID of the partition.

Fix ffa_partition_info_get by passing the received uuid down to
ffa_partition_probe so that the correct partition information is fetched.
