log spammed with "loading xx failed with error -2" since commit e40ba6d56b [replace call to fw_read_file_contents() with kernel version]

[Heiner Kallweit]

Since this commit my system log is spammed with firmware load errors. One example:

loading /lib/firmware/updates/4.5.0-rc5-next-20160226/iwlwifi-3160-16.ucode failed with error -2
loading /lib/firmware/updates/iwlwifi-3160-16.ucode failed with error -2
loading /lib/firmware/4.5.0-rc5-next-20160226/iwlwifi-3160-16.ucode failed with error -2
-> finally load attempt from /lib/firmware/iwlwifi-3160-16.ucode succeeds

Before this commit, when a load from one path in fw_path failed, silently the next path was tried.
Only if all attempts failed an error message was printed.
Now for each single failed attempt an error message is printed what doesn't make sense.
