Fixes invalid writes and crashes when doing conversions such as stereo to 5.1
channels or sample rate conversion on 5.1 channels.

It may have improved cross-platform stability, but wasn't the only place in
the encoder with bitexact issues. It is no longer needed because we have FATE
tests for float encoders using fuzzy comparison.

When using "-f x11grab -i :0.0" valgrind reports a definitely lost
memory block with this message:

==31544== 5 bytes in 1 blocks are definitely lost in loss record 1 of 2

The 5 bytes lost are the ones from param = av_strdup(":0.0"), so let's
free param in the exit path.

Also check the av_strdup() return value.

Note: calling av_free(param) even when av_strdup() fails and param is
NULL is OK and keeps the code simpler without adding another label to
skip av_free().
