[v5,0/1] Fix Guc-Err-Capture sizing warning

Message

GuC Error capture initialization calculates an estimation
buffer size for worst case scenario of all engines getting
reset. Fix the calculation change from drm_warn to drm_dbg
since its a corner case

Changes from prior revs:
   v5: - Fixed "fixes" tag + added R-b that was received from v3.
   v3: - Rebase on latest drm-tip
   v2: - Reduce the guc-log-buffer error-capture-region allocation
         from 4MB to 1MB since the corrected math uncovers the
         larger headroom available to us.
       - Modify the code comment to focus on highlighting the
         headroom we have from how min_est is caclulated.
       - Add example min-est data from real hw in the patch comment.
   v1: - Change drm_dbg to drm_warn for the case of the mis-estated
         size not being met (John Harrison).
