objtool: Silence more KCOV warnings, part 2

commit 55c78035 upstream.

Similar to GCOV, KCOV can leave behind dead code and undefined behavior.
Warnings related to those should be ignored.

The previous commit:

  6b023c78 ("objtool: Silence more KCOV warnings")

... only did so for CONFIG_CGOV_KERNEL.  Also do it for CONFIG_KCOV, but
for real this time.

Fixes the following warning:

  vmlinux.o: warning: objtool: synaptics_report_mt_data: unexpected end of section .text.synaptics_report_mt_data

Fixes: 6b023c78 ("objtool: Silence more KCOV warnings")
