scsi: core: scsi_get_device_flags_keyed(): Always return device flags
[ Upstream commit a44c9d36509c83cf64f33b93f6ab2e63822c01eb ]
Since scsi_get_device_flags_keyed() callers do not check whether or not
the returned value is an error code, change that function such that it
returns a flags value even if the 'key' argument is invalid. Note:
since commit 28a0bc4120d3 ("scsi: sd: Implement blacklist option for
WRITE SAME w/ UNMAP") bit 31 is a valid device information flag so
checking whether bit 31 is set in the return value is not sufficient to
tell the difference between an error code and a flags value.
