slirp: Remove unused variable and unused code
9634d903 disabled unused code. This patch removes what was left. If do_pty is 2, the function returns immediately, so any later checks for do_pty == 2 will always fail and can be removed together with the code which is never executed. Then variable master is unused and can be removed, too. This issue was detected by coverity.
