msm: mdss: dp: ignore PHY AUX stop error

Browse source 
Ignore the PHY AUX stop error if we receive this error
during an AUX transaction. We can safely ignore this
error and proceed to read the buffered data from the
hardware since this error happens after the data has
been received by the AUX controller hardware.
