  Make a couple of changes with regards to a new message printed in ast_read().
  
  "ast_read() called with no recorded file descriptor" is a new message added
  after a bug was discovered. Unfortunately, it seems there are a bunch of places
  that potentially make such calls to ast_read() and trigger this error message
  to be displayed. This commit does two things to help to make this message appear
  less.
  
  First, the message has been downgraded to a debug level message if dev mode is
  not enabled. The message means a lot more to developers than it does to end users,
  and so developers should take an effort to be sure to call ast_read only when
  a channel is ready to be read from. However, since this doesn't actually cause an
  error in operation and is not something a user can easily fix, we should not spam
  their console with these messages.
  
  Second, the message has been moved to after the check for any pending masquerades.
  ast_read() being called with no recorded file descriptor should not interfere with
  a masquerade taking place.
  
  This could be seen as a simple way of resolving issue #14723. However, I still want
  to try to clear out the existing ways of triggering this message, since I feel that
  would be a better resolution for the issue.
