[PATCH][next] netdevsim: Fix unsigned being compared to less than zero

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The comparison of len < 0 is always false because len is a size_t. Fix
this by making len a ssize_t instead.

Addresses-Coverity: ("Unsigned compared against 0")
Fixes: d395381909a3 ("netdevsim: Add max_vfs to bus_dev")
