ui/vnc-clipboard: fix infinite loop in inflate_buffer (CVE-2023-3255)
A wrong exit condition may lead to an infinite loop when inflating a
valid zlib buffer containing some extra bytes in the `inflate_buffer`
function. The bug only occurs post-authentication. Return the buffer
immediately if the end of the compressed data has been reached
(Z_STREAM_END).
Fixes: CVE-2023-3255
