[PATCH] libata: remove unused HSM_ST_UNKNOWN
HSM_ST_UNKNOWN is not used anywhere. Its value is zero and supposed
to serve sanity check purpose but HSM_ST_IDLE is used for that
purpose. This unused state causes confusion. After a port is
initialized but before the first command is executed, the idle hsm
state is UNKNOWN. However, once a command has completed, the idle hsm
state is IDLE. This defeats sanity check in ata_pio_task() for the
first command.
This patch removes HSM_ST_UNKNOWN and consequently make HSM_ST_IDLE
the default state.
