Matt Macy 0204d85a62 hwpmc: set default rate if event description lacks one / filter rate against misuse
Not all event descriptions have a sample rate (such as inst_retired.any)
this will restore the legacy behavior of using 65536 in that case. It also
prevents accidental API misuse that could lead to panic.
