Subject: [PATCH] brcmutil: print invalid chanspec when WARN-ing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On one of my devices I got WARNINGs when brcmfmac tried to decode
chanspec. I couldn't tell if it was some unsupported format or just a
malformed value passed by a firmware.

Print chanspec value so it's possible to debug a possible problem.
