LoongArch: Fix unsigned comparison with less than zero 

The return value from the call to get_timer_irq() is int, which can be
a negative error code. However, the return value is being assigned to an
unsigned int variable 'irq', so making 'irq' an int.

Eliminate the following coccicheck warning:
./arch/loongarch/kernel/time.c:146:5-8: WARNING: Unsigned expression compared with zero: irq < 0
