ALSA: usb-audio: Rate limit usb_set_interface error reporting
When an error occurs during USB disconnection sometimes things can go
wrong as endpoint_set_interface may end up being called repeatedly. For
example:
% dmesg --notime | grep 'usb 3-7.1.4' | sort | uniq -c | head -2
3069 usb 3-7.1.4: 1:1: usb_set_interface failed (-19)
908 usb 3-7.1.4: 1:1: usb_set_interface failed (-71)
In my case, there sometimes are hundreds of these usb_set_interface
failure messages a second when I disconnect the hub that has my USB
audio device.
These messages can take a huge amount of the kmsg ringbuffer and don't
provide any extra information over the previous ones, so ratelimit them.
