[PATCH] firmware: arm_ffa: Set handle field to zero in memory descriptor

[Balint Dobszay]

As described in commit 111a833dc5cb ("firmware: arm_ffa: Set reserved/MBZ
fields to zero in the memory descriptors") some fields in the memory
descriptor have to be zeroed explicitly. The handle field is one of these,
but it was left out from the commit, fix this now.
