The external declarations trigger warnings from ./scripts/checkpatch.pl
such as:
  WARNING: space prohibited between function name and open parenthesis '('
  #32: FILE: drivers/pci/hotplug/acpiphp.h:194:
  +extern void acpiphp_glue_init (void);

This patch removes the extraneous spaces between the function names and
open parenthesis '('.

No functional change.
