ene_lpc.c: Extract params check into a function

This allows char *p to become a local variable in check_params,
and it is allocated and freed within check_params function.
Which means init function does not need char *p anymore,
in particular does not need to free it - and this makes cleanup
after failed init easier.

As a good side effect, init function becomes easier to read.
