BUG/MEDIUM: mworker: don't register mworker_accept_wrapper() when master FD is wrong
This patch handles the case where the fd could be -1 when proc_self was
lost for some reason (environment variable corrupted or upgrade from < 1.9).
This could result in a out of bound array access fdtab[-1] and would crash.
Must be backported in every maintained versions.
