BUG/MINOR: proxy: make soft_stop() also close FDs in LI_PAUSED state

The proxies' soft_stop() function closes the FDs in all opened states
except LI_PAUSED. This means that a transient error on a listener might
cause it to turn back to the READY state if it happens exactly when a
reload signal is received.

This must be backported to all supported versions.
