Staging: comedi: fix memory leak in comedi_bond.c

Browse Source 
We allocate bdev and then krealloc the devs pointer in order to add bdev
at the end of the devpriv->devs array list.  But if for some reason this
krealloc fails, we need to free bdev before returning an error otherwise
this memory is leaked.
