Subject: [PATCH] net: bgmac: Fix an erroneous kfree() in bgmac_remove()

'bgmac' is part of a managed resource allocated with bgmac_alloc(). It
should not be freed explicitly.

Remove the erroneous kfree() from the .remove() function.

Fixes: 34a5102c3235 ("net: bgmac: allocate struct bgmac just once & don't copy it"
