video: exynos_mipi_dsi: Remove unnecessary NULL check

Browse source 
'dsim' is allocated and checked for NULL in the probe function.
Hence this check is redundant. This cleanup also fixes a potential NULL
pointer dereference error when dsim which is NULL references its member
in the error print message.
