Aleksandr Mishin 040d938487 net: wwan: iosm: Fix tainted pointer delete is case of region creation fail 
[ Upstream commit b0c9a26435 ]

In case of region creation fail in ipc_devlink_create_region(), previously
created regions delete process starts from tainted pointer which actually
holds error code value.
Fix this bug by decreasing region index before delete.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
