[PATCH][next] phy: qcom-qusb2: fix missing assignment to an error return code

[Colin King]

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

The error return code is not being assigned to ret from the call
to clk_prepare_enable and consequently the current check on ret
picks up the previous error return. Fix this by adding in the
missing assignment to ret.

Detected by CoverityScan, CID#166020 ("Logically Dead code")
