zsmalloc: use preempt.h for in_interrupt()

Browse Source 
A cosmetic change.

Commit c60369f011 ("staging: zsmalloc: prevent mappping in interrupt
context") added in_interrupt() check to zs_map_object() and 'hardirq.h'
include; but in_interrupt() macro is defined in 'preempt.h' not in
'hardirq.h', so include it instead.
