Felix Fietkau 8b0162a3dc ath5k: ignore the return value of ath5k_hw_noise_floor_calibration 
Noise floor calibration occasionally fails on Atheros hardware.
This is not fatal and can happen if there's simply too much
noise on the air. Ignoring the calibration error is the right
thing to do here, because when the error is ignored, the hardware
will still work, whereas if the error causes the driver to bail out
of a bigger configuration function and does not configure the tx
queues or the IMR (as is the case in reset.c), the hw no longer
works properly until the next reset.

* ath5k_hw_noise_floor_calibration - perform PHY noise floor calibration
*
* @ah: struct ath5k_hw pointer we are operating on

*
* This function performs a noise floor calibration of the PHY and waits for
* it to complete. Then the noise floor value is compared to some maximum
* noise floor we consider valid.
*
* Note that this is different from what the madwifi HAL does: it reads the

* calibration can take some time to finish, depending on the current channel
* use, that avoids the occasional timeout warnings we are seeing now.
*
* See the following link for an Atheros patent on noise floor calibration:
* http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL \
