msm: mdss: change error return value for lineptr sysfs entries
Changing the error return value for lineptr sysfs entries, when
the sysfs operation is not allowed. Returning EAGAIN might make
the verification tests to continuously query the sysfs nodes, or
block it. Returning EPERM will fail the query, which is expected.
