Dan Carpenter pointed out that the control flow in pt_pmu_hw_init() is a bit messy: for example the kfree(de_attrs) is entirely superfluous. Another problem is the inconsistent mixing of label based and direct return error handling. Add modern, label based error handling instead and clean up the code a bit as well. Note that we'll still do a kfree(NULL) in the normal case - this does not matter as this is an init path and kfree() returns early if it sees a NULL.
