Drivers: hv: Change hv_free_hyperv_page() to take void * argument
Currently hv_free_hyperv_page() takes an unsigned long argument, which
is inconsistent with the void * return value from the corresponding
hv_alloc_hyperv_page() function and variants. This creates unnecessary
extra casting.
Change the hv_free_hyperv_page() argument type to void *.
Also remove redundant casts from invocations of
hv_alloc_hyperv_page() and variants.
