[PATCH 1/2] DSPBRIDGE: logic error fix for SleepDSP timeout value

[Omar Ramirez Luna <omar.ramirez@ti.com>]

When leaving the loop waiting for the dsp to transition
from its power state, timeout value will be negative, therefore
a print for "timeout waiting for the dsp" won't be displayed, as
the condition to check for is !timeout.
