mshv: add bounds check on vp_index in mshv_intercept_isr()

mshv_intercept_isr() extracts vp_index from the hypervisor message
payload and uses it directly to index into pt_vp_array without
validation. handle_bitset_message() and handle_pair_message() already
validate vp_index against MSHV_MAX_VPS before array access.

Add the same MSHV_MAX_VPS bounds check for consistency with the other
message handlers.
