Haotian Zhang e6df0f649c greybus: gb-beagleplay: Fix timeout handling in bootloader functions

wait_for_completion_timeout() returns the remaining jiffies
(at least 1) on success or 0 on timeout, but never negative
error codes. The current code incorrectly checks for negative
values, causing timeouts to be ignored and treated as success.

Check for a zero return value to correctly identify and
handle timeout events.
