[PATCH] x86/hyperv: Use pointer from memcpy() call for assignment in hv_crash_setup_trampdata()

[Markus Elfring]

A pointer was assigned to a variable. The same pointer was used for
the destination parameter of a memcpy() call.
This function is documented in the way that the same value is returned.
Thus convert two separate statements into a direct variable assignment for
the return value from a memory copy action.

The source code was transformed by using the Coccinelle software.
