core/hwtimer: disable interrupts in hwtimer_remove
...
Before only the hardware timer's own interrupt was being disabled.
This led to a race condition in the following scenario:
```
Thread1:
hwtimer_remove()
hwtimer_arch_disable_interrupt();
// INTERRUPT -> Thread2 (which has a higher priority than Thread1) gets scheduled
Thread2:
...
hwtimer_remove()
hwtimer_arch_disable_interrupt(); // hwtimer interrupt is already disabled
...
hwtimer_arch_enable_interrupt();
...
// yield | terminate -> Thread1 gets scheduled again
Thread1:
... // these instructions are being run with the hwtimer interrupt enabled
hwtimer_arch_enable_interrupt(); // hwtimer interrupt is already enabled
```
Fixes #924
