drm/xe/guc: Fix CFI violation in debugfs access.

Browse source

[ Upstream commit 4cb1b32713 ]

xe_guc_print_info is void-returning, but the function pointer it is
assigned to expects an int-returning function, leading to the following
CFI error:

[  206.873690] CFI failure at guc_debugfs_show+0xa1/0xf0 [xe]
(target: xe_guc_print_info+0x0/0x370 [xe]; expected type: 0xbe3bc66a)

Fix this by updating xe_guc_print_info to return an integer.
