liquidio: fix bug in soft reset failure detection
The code that detects a failed soft reset of Octeon is comparing the wrong
value against the reset value of the Octeon SLI_SCRATCH_1 register,
resulting in an inability to detect a soft reset failure. Fix it by using
the correct value in the comparison, which is any non-zero value.
Fixes: f21fb3ed364b ("Add support of Cavium Liquidio ethernet adapters")
Fixes: c0eab5b3580a ("liquidio: CN23XX firmware download")
