[PATCH 4/4] drm/msm/dsi: Remove set but not used variable 'lp'

[zhengbin]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/msm/dsi/dsi_host.c: In function dsi_cmd_dma_rx:
drivers/gpu/drm/msm/dsi/dsi_host.c:1302:7: warning: variable lp set but not used [-Wunused-but-set-variable]

It is not used since commit a689554ba6ed ("drm/msm:
Initial add DSI connector support")
