caif: cleanup: remove duplicate checks 

"phyinfo" can never be null here because we assigned it an address, so I
removed both the assert and the second check inside the if statement.  I
removed the "phyinfo->phy_layer != NULL" check as well because that was
asserted earlier.

Walter Harms suggested I move the "phyinfo->phy_ref_count++;" outside
the if condition for readability, so I have done that.
