[PATCH] drm/i915: remove redundant variable hw_check

[Chris Wilson]

Quoting Colin King (2017-09-14 17:21:54)
> From: Colin Ian King <colin.king at canonical.com>
> 
> hw_check is being assigned and updated but is no longer being read,
> hence it is redundant and can be removed.
> 
> Detected by clang scan-build:
> "warning: Value stored to 'hw_check' during its initialization
> is never read"
> 
> Fixes: f6d1973db2d2 ("drm/i915: Move modeset state verifier calls")
