virtio/rng: Fix build warning from min()
On a 32-bit build GCC complains about the min() parameters:
include/linux/kernel.h:36:24: error: comparison of distinct pointer types lacks a cast [-Werror]
36 | (void) (&_min1 == &_min2); \
| ^~
virtio/rng.c:78:34: note: in expansion of macro 'min'
78 | iov[0].iov_len = min(iov[0].iov_len, 256UL);
| ^~~
Use min_t() instead
Fixes: bc23b9d9b152 ("virtio/rng: return at least one byte of entropy")
