Ensure handle is valid and pm_errno is reset when calling into API
We didn't do due diligence before and ensure prior pm_errno values weren't influencing what happened in further ALPM calls. I observed one case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that flag persisting the entire time we were calling library code. Add a new CHECK_HANDLE() macro that does two things: 1) ensures the handle variable passed to it is non-NULL and 2) clears any existing pm_errno flag set on the handle. This macro can replace many places we used the ASSERT(handle != NULL, ...) pattern before. Several other other places only need a simple 'set to zero' of the pm_errno field.
