Currently, the decoding of RR frequency list information elements can give
wrong results when the list was encoded using 1024, 512, 256 or 128 ranges.
In fact function f_k() used in the decoding is buggy and gives incorrect
results.
The attached patch replace the function with a valid one as specified in 3GPP
44.018 annex J.5.
