[PATCH] documentation: key header files: fix member variable description warnings

[Alissa Guo <guoalissa@gmail.com>]

Fix the following documentation compilation warnings from missing member variable descriptions when 'make htmldocs' is called:

Fixed misspelling of @j_transaction_overhead to @j_transaction_overhead_buffers in ./include/linux/jbd2.h:1303

Add description of 'target_rr_divider' in  ./include/drm/display/drm_dp_helper.h

Add description of 'width' and 'height' in struct 'drm_plane_size_hint' in ./include/uapi/drm/drm_mode.h

Effects:

The following warnings should no longer arise upon 'make htmldocs'

./include/linux/jbd2.h:1303: warning: Function parameter or struct member 'j_transaction_overhead_buffers' not described in 'journal_s'
./include/linux/jbd2.h:1303: warning: Excess struct member 'j_transaction_overhead' description in 'journal_s'
./include/drm/display/drm_dp_helper.h:127: warning: Function parameter or struct member 'target_rr_divider' not described in 'drm_dp_as_sdp'
./include/uapi/drm/drm_mode.h:869: warning: Function parameter or struct member 'width' not described in 'drm_plane_size_hint'
./include/uapi/drm/drm_mode.h:869: warning: Function parameter or struct member 'height' not described in 'drm_plane_size_hint'
