Subject: [PATCH] EDAC: Fix memory leak in i5100_init_one

In the implementation of i5100_init_one(), the allocated mci is not
correctly released in cases of failure. The release via edac_mc_free()
should be reached by label bail_einj and subsequents.

Fixes: 52608ba20546 ("i5100_edac: probe for device 19 function 0")
