[PATCH v1 0/2] ucounts: Fix rlimit max values check

Checking the rlimit value specified in init_user_ns from the created userns does
not work properly. The issue is that the maximum value is taken by the same
rules as for ucounts. Because of this, we check the current rlimit counter value
with RLIM_INFINITY in init_user_ns.
