Description

Don't fail step out if remote server doesn't implement qMemoryRegionInfo

Summary:
The return address validation in D71372 will fail if the memory permissions can't be determined. Many embedded stubs either don't implement the qMemoryRegionInfo packet, or don't have memory permissions at all.

Remove the return from the if clause that calls GetLoadAddressPermissions, so this call failing doesn't cause the step out to abort. Instead, assume that the memory permission check doesn't apply to this type of target.
