Gyeyoung Baek 74570e12b4 accel/rocket: Fix prep_bo ioctl leaking positive return from dma_resv_wait_timeout() 
dma_resv_wait_timeout() returns a positive 'remaining jiffies' value
on success, 0 on timeout, and -errno on failure.

rocket_ioctl_prep_bo() returns this 'long' result from an int-typed
ioctl handler, so positive values reach userspace as bogus errors.
Explicitly set ret to 0 on the success path.

Fixes: 525ad89dd9 ("accel/rocket: Add IOCTLs for synchronizing memory accesses")
