CIFS: Fix a possible invalid memory access in smb2_query_symlink() [ Upstream commit 7893242e2465aea6f2cbc2639da8fa5ce96e8cc2 ] During following a symbolic link we received err_buf from SMB2_open(). While the validity of SMB2 error response is checked previously in smb2_check_message() a symbolic link payload is not checked at all. Fix it by adding such checks.
