ata: libata-sff: Fix compilation warning in ata_sff_lost_interrupt()

Browse Source 
When returning false, ata_sff_altstatus() does not return any status
value, resulting in a compilation warning in ata_sff_lost_interrupt()
("uninitialized symbol 'status'"). Fix this by initializing the local
variable "status" to 0.
