binarybuffer: str_to_buf(): rename buf_len as buf_bitsize

Browse Source 
The name 'buf_len' is misleading, as it usually refers to the byte
length of a buffer. Here we use it for the length in bits.

Rename it as 'buf_bitsize'.
While there, fix checkpatch error by changing the index type to
'unsigned int'.
