bnx2x: use correct format characters

When compiling with -Wformat, clang emits the following warnings:

drivers/net/ethernet/broadcom/bnx2x/bnx2x_link.c:6181:40: warning: format

The types of these arguments are unconditionally defined, so this patch
updates the format character to the correct ones for ints and unsigned
ints.
