Thread-topic: [Xen-devel] [PATCH] VT-d: handle return value of deassign_device

deassign_device may fail, so need to capture its failure for appropriate 
handling. This patch captures return values of deassign_device, and prints 
error messages if it fails.

In addition, this patch also fixes some code style issues.
