[PATCH] acpi: method: skip over bad method_handle and failed message type

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

When fetching the method_handle and the message type there are
issues warning about failures but no real error handling. This
can lead to an uninitialized method_handle being passed into
AcpiGetType that can cause an uninitialized pointer read. Fix
these failures by continuing on to the next method inthe list.

Addresses-Coverity: ("Uninitialized pointer read")
Fixes: e2a21f8d75d8 ("acpi: method: skip scope names in method_evaluate_method")
