enic: Fix 64 bit divide on 32bit system
Division of a 32 bit number by a 64 bit number causes the following link
error introduced by
7c2ce6e60f703 "enic: Add support for adaptive interrupt coalescing"
drivers/built-in.o: In function `enic_poll_msix':
enic_main.c:(.text+0x48710a): undefined reference to `__udivdi3'
make: *** [vmlinux] Error 1
Since numerator is 32 bit, convert denominator to 32 bit accordingly.
Fixes: 7c2ce6e60f703 ("enic: Add support for adaptive interrupt coalescing")
