avcodec/xbmdec: get_nibble() minor speed increase, and binary reduction

Replace av_isxdigit(*ptr) and convert(*ptr) with get_nibble(*ptr) which
returns a valid nibble=={0x00..0x0f} or false==255 for all other values.
This way we only need to work with *ptr once instead of twice.

Removing inline av_isxdigit(x) functions also shrinks executable size.
