[PATCH] Fix implicit cast warning in test_klp_state.c

The function `klp_get_state` returns an `int` value, but the variable
`loglevel_state` is of type `struct klp_state *` and thus does an
implicit cast. Explicitly casting these values fixes:

- warning: assignment to ‘struct klp_state *’ from ‘int’
makes pointer from integer without a cast [-Wint-conversion]

on lines 38, 55, 68 and 80 of test_klp_state.c
