    linux-record: Fix bad fall-through for pipe/pipe2
    
    This patch added handling for some syscalls to linux-record.c:
    
      https://sourceware.org/ml/gdb-patches/2015-10/msg00452.html
    
    But for both `pipe' and `pipe2' the patch lacks a statement after an
    `if', such that the following `break' is interpreted as the `if'-body
    instead.
    
    This adds the missing (return-) statements for the conditionals.
    
    gdb/ChangeLog:
    
    	* linux-record.c (record_linux_system_call): Add missing return
    	statements to handling of pipe and pipe2 syscalls.
