[PATCH] ioemu: Add SEEK_STAT in all non-error cases except sleep request

[PATCH] ioemu: Add SEEK_STAT in all non-error cases except sleep request

[Samuel Thibault]

ioemu: Add SEEK_STAT in all non-error cases except sleep request, since
our seek times are virtually 0.  Although this flag is deprecated by
newer ATA standards, Linux at least checks it for CD drives, and would
timeout in some cases if we do not set it.
