Check the call to lseek in
kexec/arch/ppc64/fs2dt.c:add_usable_mem_property-lseek() for
errors.
Appart from being a good idea, this is a preparatory patch to remove
the farily bogus scemantic of checking and setting errno some time later in
functions in kexec/arch/ppc64/fs2dt.c to see if an error occured somewhere.
