smb/client: fix buffer size for smb311_posix_qinfo in smb2_compound_op()

Browse source 
Use `sizeof(struct smb311_posix_qinfo)` instead of sizeof its pointer,
so the allocated buffer matches the actual struct size.

Fixes: 6a5f6592a0 ("SMB311: Add support for query info using posix extensions (level 100)")
