[PATCH 2/2] drm/exec: Fix the drm_exec_retry parameter documentation

[Weijie Yuan]

When running 'make htmldocs', Sphinx complains:

WARNING: ./include/drm/drm_exec.h:162 function parameter '_exec' not described in 'drm_exec_retry'
WARNING: ./include/drm/drm_exec.h:162 Excess function parameter 'exec' description in 'drm_exec_retry' (did you mean one of: '_exec')
WARNING: ./include/drm/drm_exec.h:162 function parameter '_exec' not described in 'drm_exec_retry'
WARNING: ./include/drm/drm_exec.h:162 Excess function parameter 'exec' description in 'drm_exec_retry' (did you mean one of: '_exec')

If duplicate, please ignore.

Thanks.

drm_exec_retry() takes _exec, but its kernel-doc describes exec.
This produces missing and excess parameter description warnings.

Use the macro parameter's actual name in the comment.
