[x265] bframe bias config document and the comments of bFrameBias dismatch

[Ximing Cheng]

The x265 developer documents on --bframe-bias <integer> said "The higher
the bias the more likely x265 is to use B frames", but the comments in the
x265.h says "It may be a positive value (making B frames appear more
expensive, which causes the lookahead to chose more P frames) or negative,
which makes the lookahead chose more B frames"

I have read the source code of the X265_B_ADAPT_FAST lookahead B frames
adapt, I found the larger value of the --bframe-bias will lead
more probability to choose the B frame, so the comments is mistaken.

I don't know whether it is right.

Thanks!
