drm/amdkfd: Rectify the jiffies calculation error with milliseconds v2
The timeout in milliseconds should not be regarded as jiffies. This commit fixed that. v2: - use msecs_to_jiffies - change timeout_ms parameter to unsigned int to match msecs_to_jiffies Signed-off-by: Yong Zhao <[email protected]> Signed-off-by: Felix Kuehling <[email protected]> Signed-off-by: Oded Gabbay <[email protected]>
