KVM: x86: Optimize local variable in start_sw_tscdeadline()

Browse source

Change the data type of the local variable this_tsc_khz to u32 because
virtual_tsc_khz is also declared as u32.

Since do_div() casts the divisor to u32 anyway, changing the data type
of this_tsc_khz to u32 also removes the following Coccinelle/coccicheck
warning reported by do_div.cocci:

  WARNING: do_div() does a 64-by-32 division, please consider using div64_ul instead
