Iff dma_map_single() fails, 'rxdesc' should point to the last filled RX
descriptor, so that it can be marked as the last one, however the driver
would have already advanced it by that time. In order to fix that, only
fill an RX descriptor once all the data for it is ready.

In a low memory situation, if netdev_alloc_skb() fails on a first RX ring
loop iteration in sh_eth_ring_format(), 'rxdesc' is still NULL. Avoid
kernel oops by adding the 'rxdesc' check after the loop.

The stub helper functions for the newly added kcm_proc_init/exit interfaces
are defined as 'static' in a header file, which leads to build warnings for
each file that includes them without calling them:
include/net/kcm.h:183:12: error: 'kcm_proc_init' defined but not used [-Werror=unused-function]
include/net/kcm.h:184:13: error: 'kcm_proc_exit' defined but not used [-Werror=unused-function]
This marks the two functions as 'static inline' instead, which avoids the
warnings and is obviously what was meant here.
