Fix compile error in pridump.c.

With gcc 4.6.3 it's possible to get the following error:

  $ make
  gcc -Wall -Werror -Wstrict-prototypes -Wmissing-prototypes -g -fPIC  -O2  -MD -MT pridump.o -MF .pridump.o.d -MP -c -o pridump.o pridump.c
  pridump.c: In function \u2018pri_bridge\u2019:
  pridump.c:117:1: error: no return statement in function returning non-void [-Werror=return-type]
  cc1: all warnings being treated as errors
  make: *** [pridump.o] Error 1

Changing the function return value to void fixes the issue since there
were no places in the code that used the return value.

(closes issue PRI-143)
