sub: don't busy loop if the player is paused for cache 

When updating subtitles while paused, mpv waits until a packet is
available. However in the case of a network stream, it is possible that
mpv will pause itself when buffering for cache reasons. This makes that
particular loop do a busy loop and can take a long time depending on
network streams. Simply just don't do the loop here if we are paused for
cache reasons. Fixes #13077.
