smb: client: handle max length for SMB symlinks
We can't use PATH_MAX for SMB symlinks because
(1) Windows Server will fail FSCTL_SET_REPARSE_POINT with
STATUS_IO_REPARSE_DATA_INVALID when input buffer is larger than
16K, as specified in MS-FSA 2.1.5.10.37.
(2) The client won't be able to parse large SMB responses that
includes SMB symlink path within SMB2_CREATE or SMB2_IOCTL
responses.
Fix this by defining a maximum length value (4060) for SMB symlinks
that both client and server can handle.
