smb/client: fix buffer size for smb311_posix_qinfo in SMB311_posix_query_info()
SMB311_posix_query_info() is currently unused, but it may still be used in
some stable versions, so these changes are submitted as a separate patch.
Use `sizeof(struct smb311_posix_qinfo)` instead of sizeof its pointer,
so the allocated buffer matches the actual struct size.
Fixes: b1bc1874b885 ("smb311: Add support for SMB311 query info (non-compounded)")
