libdecnumber: Fix decNumberSetBCD
Fix a simple bug in the decNumberSetBCD() function. This function encodes a decNumber with "n" BCD digits. The original code erroneously computed the number of declets from the dn argument, which is the output decNumber value, and hence may contain garbage. Instead, the input "n" value is used.
