[PATCH][V2] net: dsa: b53: remove redundant null check on dev

[Colin King <colin.king@canonical.com>]

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

The pointer dev can never be null, the null check is redundant
and can be removed. Cleans up a static analysis warning that
pointer priv is dereferencing dev before dev is being null
checked.

Addresses-Coverity: ("Dereference before null check")

V2: Remove null check rather than add b53_srab_intr_set call into a null
    check statement block.
    Rephrase commit Subject to reflect the change in the fix.
