net: sfp: fix memory leak in sfp_probe()

Browse source 
[ Upstream commit 0a18d802d6 ]

sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When
devm_add_action() fails, sfp is not freed, which leads to a memory leak.

We should use devm_add_action_or_reset() instead of devm_add_action().
