[PATCH] qemuProcessSetupRawIO: Refactor return value and remove useless #ifdef

[Peter Krempa <pkrempa@xxxxxxxxxx>]

The function can return directly rather than setting 'ret' as there's no
cleanup.

It also doesn't make sense to conditionally compile out the 'break'
statement when checking whether a disk has rawio enabled if
'CAP_SYS_RAWIO' is _not_ defined as the function will still behave the
same.
