mac80211: add iw command wrapper with error logging 

Currently it's close to impossible to tell what part of mac80211 setup
went wrong. Errors logged into system log look like this:
radio0 (6155): command failed: No error information (-524)
radio0 (6155): command failed: Not supported (-95)
radio0 (6155): command failed: I/O error (-5)
radio0 (6155): command failed: Too many open files in system (-23)

With this commit change it's getting clear:
command failed: No error information (-524)
Failed command: iw dev wlan0 del
command failed: Not supported (-95)
Failed command: iw phy phy0 set antenna_gain 0
command failed: I/O error (-5)
Failed command: iw phy phy0 set distance 0
command failed: Too many open files in system (-23)
Failed command: iw phy phy0 interface add wlan0 type __ap
