coding: Refactor function to avoid gcc false positive warn

"""
/libosmocore/src/coding/gsm0503_coding.c: In function 'osmo_conv_decode_ber_punctured':
/libosmocore/src/coding/gsm0503_coding.c:563:31: error: 'coded_len' may be used uninitialized [-Werror=maybe-uninitialized]

This error is really a false positive. However, it is true that the code
used to be a bit more complex than required, since the 2 later conditions
could be inside the first one.
Let's simply do early termination to simplify the function, and get rid
of the gcc warning.
