ZEND_NS_NAMED_FE(ns, zend_name, name, arg_info)

was resulting in a function declaration of:

ns\"zend_name"()

including the errant quotes.

This diff corrects that.  There are currently no uses of ZEND_NS_NAMED_FE
in core and reason to believe that there are no uses in the wild either.

This is patch already applied in some linux distro.
