while playing with gcc 4.1 -Wextra warnings, I came across this one:

drivers/net/3c515.c:1027: warning: comparison of unsigned expression >= 0 is always true

Since i is unsigned the >= 0 check in the for loop is always true,
so we might spin there forever unless the if condition triggers.
Since i is only used in this loop, this patch changes it to
an integer.
