nrf5x: Fix reception of large ISO packets 

ISO packet size is up to 1023 for full speed device.
Upon completion of ISO reception, reported length of incoming packet
was truncated to one byte only.
This results in incorrect data stream for higher bit rates
48 samples * 4 bytes per sample * 2 channels = 384 bytes of data
and 128 was reported.

There is no change in logic extending xact_len to uint16_t fixes the issue.
