John Harrison a4be3dca53 drm/i915: Fix up locking around dumping requests lists 
The debugfs dump of requests was confused about what state requires
the execlist lock versus the GuC lock. There was also a bunch of
duplicated messy code between it and the error capture code.

So refactor the hung request search into a re-usable function. And
reduce the span of the execlist state lock to only the execlist
specific code paths. In order to do that, also move the report of hold
count (which is an execlist only concept) from the top level dump
function to the lower level execlist specific function. Also, move the
execlist specific code into the execlist source file.

v2: Rename some functions and move to more appropriate files (Daniele).
v3: Rename new execlist dump function (Daniele)

Fixes: dc0dad365c ("drm/i915/guc: Fix for error capture after full GPU reset with GuC")
