Fix uninitialized memory bug in hsaKmtWaitOnMultipleEvents

Brabhsáil Foinse 
Use calloc to allocate event data. Otherwise random data may be filled
in for events that haven't actually signalled. This could trigger the
VM fault handler in the Runtime when no VM fault actually happened and
lead to intermittent HSA conformance test failures.
