Hello fixeria, pespin, laforge, Jenkins Builder,

rx_check_imei_req(): fix IMEI bounds checking

IMEIs (without the checksum) always have 14 digits. Replace the previous
check (length <= 14) with a proper one (length == 14) and set the buffer
to the right size. While at it, add the return code of
gsm48_decode_bc_number2() to the error log message.

I have tested with new TTCN3 tests, that the length check is working
properly now.
