[PATCH net-next] liquidio: fix bug in soft reset failure detection

[Felix Manlunas]

From: Derek Chickles <derek.chick...@cavium.com>

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.
