Hans de Goede f7aff3b928 HID: logitech-hidpp: Silence intermittent get_battery_capacity errors
[ Upstream commit 61005d65b6c7dcf61c19516e6ebe5acc02d2cdda ]

My Logitech M185 (PID:4038) 2.4 GHz wireless HID++ mouse is causing
intermittent errors like these in the log:

[11091.034857] logitech-hidpp-device 0003:046D:4038.0006: hidpp20_batterylevel_get_battery_capacity: received protocol error 0x09
[12388.031260] logitech-hidpp-device 0003:046D:4038.0006: hidpp20_batterylevel_get_battery_capacity: received protocol error 0x09
[16613.718543] logitech-hidpp-device 0003:046D:4038.0006: hidpp20_batterylevel_get_battery_capacity: received protocol error 0x09
[23529.938728] logitech-hidpp-device 0003:046D:4038.0006: hidpp20_batterylevel_get_battery_capacity: received protocol error 0x09

We are already silencing error-code 0x09 (HIDPP_ERROR_RESOURCE_ERROR)
errors in other places, lets do the same in
hidpp20_batterylevel_get_battery_capacity to remove these harmless,
but scary looking errors from the dmesg output.
