gpu: nvgpu: fix cond_wait return value in channel poll worker
The return value from NVGPU_COND_WAIT_INTERRUPTIBLE in
channel poll worker is wrongly compared with 0 and the
boolean result is assigned to ret value used subsequently.
Instead, the direct return value from
NVGPU_COND_WAIT_INTERRUPTIBLE should be used.
This bug seems remnant of the following patch which moved
the handling from 'wait_event_timeout' to 'NVGPU_COND_WAIT'.
