smb/client: fix buffer size for smb311_posix_qinfo in smb2_compound_op()
[ Upstream commit 12c43a062acb0ac137fc2a4a106d4d084b8c5416 ]
Use `sizeof(struct smb311_posix_qinfo)` instead of sizeof its pointer,
so the allocated buffer matches the actual struct size.
Fixes: 6a5f6592a0b6 ("SMB311: Add support for query info using posix extensions (level 100)")
