ath10k-ct: activate user space firmware loading again
This backports a patch from kernel 4.14 to the ath10k-ct version based on kernel 4.13. Some devices are using a user space script to load the calibration data from the flash and this was not trigged any more. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

+Subject: [PATCH] ath10k: activate user space firmware loading again
+
+In commit 9f5bcfe93315 ("ath10k: silence firmware file probing
+warnings") the firmware loading was changed from request_firmware() to
+request_firmware_direct() to silence some warnings in case it fails.
+request_firmware_direct() directly searches in the file system only and
+does not send a hotplug event to user space in case it could not find
+the firmware directly.
+In LEDE we use a user space script to extract the calibration data from
+the flash memory which gets triggered by the hotplug event. This way the
+firmware gets extracted from some vendor specific partition when the
+driver requests this firmware. This mechanism does not work any more
+after this change.
+
+Fixes: 9f5bcfe93315 ("ath10k: silence firmware file probing warnings")
