x86/hyperv: Clean up hv_map/unmap_interrupt() return values

Fix the return values of these hypercall helpers so they return
a negated errno either directly or via hv_result_to_errno().

Update the callers to check for errno instead of using
hv_status_success(), and remove redundant error printing.

While at it, rearrange some variable declarations to adhere to style
guidelines i.e. "reverse fir tree order".
