Currently code handles H_FUNCTION, H_SUCCESS, H_HARDWARE return codes.
However hcall_vphn can return other return codes. Now it also handles
H_PARAMETER return code. Also the rest return codes are handled under the
default case.

However:
+ case H_PARAMETER:
+ pr_err_ratelimited("hcall_vphn() was passed an invalid parameter. "
+ "Disabling polling...\n");
Consider including the bad parameter value in the message?
