[PATCH] net: qed: Fix the use of NULL pointer

[Jiasheng Jiang]

If the return value of 'IS_PF(cdev)' is False, then 'p_ptt'
is NULL and the check 'if (IS_PF(cdev) && !p_ptt)' can be
passed through.
Then 'p_ptt' will be used in qed_memcpy_to().
However, 'p_ptt' will be used there, such as 'p_ptt->idx'.
Thus it might be better to fix it.

Fixes: dacd88d ("qed: IOV l2 functionality")
