[PATCH] zsmalloc: use preempt.h for in_interrupt()

[Sergey Senozhatsky]

A cosmetic change.

Commit c60369f01125 ("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.
