RF calibration on USB adapters (RTL8922AU) fails frequently because the
timeout values in rtw89_phy_rfk_report_wait() are designed for PCIe and
too tight for USB H2C/C2H round-trip latency.

Patch 1 applies a 4x timeout multiplier for USB devices, based on
measured calibration times from two independent testers across 2.4GHz,
5GHz, and 6GHz bands.

Patch 2 makes calibration timeouts non-fatal on USB, since the radio
continues to operate correctly despite occasional incomplete
calibrations. PCIe error handling is unchanged.

This is based on Ping-Ke's suggestion in the RTL8922AU support thread:
