Subject: [PATCH 5.17 0260/1126] crypto: qat - fix initialization of pfvf rts_map_msg structures

From: Giovanni Cabiddu <giovanni.cabiddu@...el.com>

[ Upstream commit 44dbd0c61bf1480be55dbb0cac793d861d1957b9 ]

Initialize fully the structures rts_map_msg containing the ring to
service map from the host.

This is to fix the following warning when compiling the QAT driver
using the clang compiler with CC=clang W=2:

    drivers/crypto/qat/qat_common/adf_pfvf_vf_msg.c:144:51: warning: missing field 'map' initializer [-Wmissing-field-initializers]
            struct ring_to_svc_map_v1 rts_map_msg = { { 0 }, };
                                                             ^
