ata: libata: make ata_host_suspend() *void*

Browse Source 
ata_host_suspend() always returns 0, so the result checks in many drivers
look pointless.  Let's make this function return *void* instead of *int*.

Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
