[PATCH] phy: sunplus: Fix a memory leak in update_disc_vol()

[Christophe JAILLET]

'otp_v', allocated by nvmem_cell_read(), is leaking.
It must be freed before leaving the function to avoid a leak.

Fixes: 99d9ccd97385 ("phy: usb: Add USB2.0 phy driver for Sunplus SP7021")
Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

This patch is speculative and based on comparison on the usage of
nvmem_cell_read() in other driver.

Review with care.
