[PATCH] bnx2x: truncate value to original sizing

[PATCH] bnx2x: truncate value to original sizing

[Bill Wendling]

The original behavior was to print out unsigned short or unsigned char
values. The change in commit d65aea8e8298 ("bnx2x: use correct format
characters") prints out the whole value if not truncated. So truncate
the value to an unsigned {short|char} to retain the original behavior.

Fixes: d65aea8e8298 ("bnx2x: use correct format characters")
