[PATCH] drm/drm_exec: fix kernel-doc string in drm_exec_retry

[Jakov Novak]

Building the documentation currently with make htmldocs gives the
following errors:

  WARNING: ./include/drm/drm_exec.h:159 function parameter '_exec' not described in 'drm_exec_retry'
  WARNING: ./include/drm/drm_exec.h:159 Excess function parameter 'exec' description in 'drm_exec_retry' (did you mean one of: '_exec')
  WARNING: ./include/drm/drm_exec.h:159 function parameter '_exec' not described in 'drm_exec_retry'
  WARNING: ./include/drm/drm_exec.h:159 Excess function parameter 'exec' description in 'drm_exec_retry' (did you mean one of: '_exec')

This is because the parameter is defined without the underscore in the
kernel-doc string. Change the parameter name to add the missing
underscore.

Fixes: bba175a2d4be ("drm/exec, drm/xe: Avoid abusing the drm_exec retry pointer")
