Net: DSA: Fix checking for get_phy_flags function

The check for the presence or not of the optional switch function
get_phy_flags() called the function, rather than checked to see if it
is a NULL pointer. This causes a derefernce of a NULL pointer on all
switch chips except the sf2, the only switch to implement this call.
