LOG: [Sanitizer] Call Die() instead of Abort() when failed to reserve shadow memory range (#107833)

I grep the code and find that `Abort()` is only called in `Die()` when
the flag `abort_on_error` is set.
Thus, if reserving shadow memory range fails, `Die()` rather than
`Abort()` should be called. In this case, the flag `abort_on_error` will
be respected and the die callbacks will be called.
