[PATCH][next] phy: ti: ensure priv is not null before dereferencing it

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Currently priv is being dereferenced before priv is being null checked.
Fix this by moving the null check on priv before the dereference.

Detected by CoverityScan, CID#1476018 ("Dereference before null check")

Fixes: 92b58b34741f ("phy: ti: introduce phy-gmii-sel driver")
