[PATCH] mm/mapping_dirty_helpers: enhance the kernel-doc markups

[Alex Shi]

Add and change parameter explanation for wp_pte and clean_record_pte, to
avoid W1 warning:
mm/mapping_dirty_helpers.c:34: warning: Function parameter or member
'end' not described in 'wp_pte'
mm/mapping_dirty_helpers.c:88: warning: Function parameter or member
'end' not described in 'clean_record_pte'
