drm/msm/dsi: invalid parameter check in msm_dsi_phy_enable
commit 5e761a2287234bc402ba7ef07129f5103bcd775c upstream.
The function performs a check on the "phy" input parameter, however, it
is used before the check.
Initialize the "dev" variable after the sanity check to avoid a possible
NULL pointer dereference.
Fixes: 5c8290284402b ("drm/msm/dsi: Split PHY drivers to separate files")
Addresses-Coverity-ID: 1493860 ("Null pointer dereference")
