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

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. Fixes: 03c0e84 ("ata: libata-sff: refactor ata_sff_altstatus()") Cc: [email protected] Signed-off-by: Damien Le Moal <[email protected]>
