relayfs: replace BUG() with WARN_ON() in relay_late_setup_files()
Impact: turn boot crash into boot warning
This BUG() can trigger:
[ 16.684131] initcall fail_page_alloc_debugfs+0x0/0xc1 returned 0 after 0 usecs
[ 16.692035] calling kmemtrace_setup_late+0x0/0xd5 @ 1
[ 16.700087] relay_late_setup_files: CPU 1 has no buffer, it must have!
[ 16.704044] ------------[ cut here ]------------
[ 16.708030] kernel BUG at kernel/relay.c:680!
[ 16.708030] invalid opcode: 0000 [#1] SMP DEBUG_PAGEALLOC
[ 16.708030] last sysfs file:
[ 16.708030]
[ 16.708030] Pid: 1, comm: swapper Not tainted (2.6.28-tip-03903-g9a39f58-dirty #13207) System Product Name
[ 16.708030] EIP: 0060:[<c01604ae>] EFLAGS: 00010246 CPU: 1
[ 16.708030] EIP is at relay_late_setup_files+0x8c/0x176
Reduce it to a more reportable WARN_ONCE().
