can: pch_can: fix error passive level test The test (((errc & PCH_REC) >> 8) > 127) would always be false because the receive error counter ((errc & PCH_REC) >> 8) is at most 127, where PCH_REC is defined as 0x7f00. To test whether the receive error counter has reached the error passive level, the RP bit (15) should be used.
