[PATCH] zd1211rw: Fixed endianess issue with length info tag detection

Discovered a problem while accessing www.python.org on my PPC32.
The problem was pretty consistent for all sticks. The reason was
that while testing for the length info tag, I ignored the
endianess of the host system.

Please recognize that converting the constant to little endian, we
create faster code.
