ath10k: silence firmware file probing warnings
Firmware files are versioned to prevent older
driver instances to load unsupported firmware
blobs. This is reflected with a fallback logic
which attempts to load several firmware files.
This however produced a lot of unnecessary
warnings sometimes confusing users and leading
them to rename firmware files making things even
more confusing.
Hence use request_firmware_direct() which does not
produce extra warnings. This shouldn't really
break anything because most modern systems don't
rely on udev/hotplug helpers to load firmware
files anymore. For example it was confirmed that
LEDE does not user helper.
This also fixes a 60 second delay per _each_
unexistent firmware/calibration file with distros
which have CONFIG_FW_LOADER_USER_HELPER_FALLBACK
enabled, RHEL being a notable example. Using
ath10k with firmware-2.bin this might end up
into a five minute delay in boot.
