Remove multiple kfree statement from phram_setup() in phram.c

Signed-off-by: Saurav Girepunje <saurav.girepunje@gmail.com>

Change in v1:

- Add change suggested by Miquel Raynal <miquel.raynal@bootlin.com>
  "The goto statement should not describe from where it is called but the
   action it is supposed to take. 'goto free_nam;' would be better."
