Subject[PATCH] net: ehea: Mark expected switch fall-through
Mark switch cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/net/ethernet/ibm/ehea/ehea_main.c: In function 'ehea_mem_notifier':
include/linux/printk.h:311:2: warning: this statement may fall through [-Wimplicit-fallthrough=]
printk(KERN_INFO pr_fmt(fmt), ##__VA_ARGS__)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/ibm/ehea/ehea_main.c:3253:3: note: in expansion of macro 'pr_info'
pr_info("memory offlining canceled");
^~~~~~~
drivers/net/ethernet/ibm/ehea/ehea_main.c:3256:2: note: here
case MEM_ONLINE:
^~~~

Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.
