[PATCH 4.9 37/49] tracing: Fix SKIP_STACK_VALIDATION=1 build due to bad merge with -mrecord-mcount

[Greg Kroah-Hartman]

From: Greg Thelen <gthelen@xxxxxxxxxx>

commit ed7d40bc67b8353c677b38c6cdddcdc310c0f452 upstream.

Non gcc-5 builds with CONFIG_STACK_VALIDATION=y and
SKIP_STACK_VALIDATION=1 fail.
Example output:
  /bin/sh: init/.tmp_main.o: Permission denied

commit 96f60dfa5819 ("trace: Use -mcount-record for dynamic ftrace"),
added a mismatched endif.  This causes cmd_objtool to get mistakenly
set.

Relocate endif to balance the newly added -record-mcount check.
