[PATCH] staging: fsl-dpaa2/ethsw: fix memory leak of switchdev_work

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

In the default event case switchdev_work is being leaked because
nothing is queued for work. Fix this by kfree'ing switchdev_work
before returning NOTIFY_DONE.

Addresses-Coverity: ("Resource leak")
Fixes: 44baaa43d7cc ("staging: fsl-dpaa2/ethsw: Add Freescale DPAA2 Ethernet Switch driver")
