ocfs2: Fix use of slab data with sendpage
ocfs2 uses kzalloc() to allocate buffers for o2net_hand, o2net_keep_req and
o2net_keep_resp and then passes these to sendpage. This isn't really
allowed as the lifetime of slab objects is not controlled by page ref -
though in this case it will probably work. sendmsg() with MSG_SPLICE_PAGES
will, however, print a warning and give an error.
Fix it to use folio_alloc() instead to allocate a buffer for the handshake
message, keepalive request and reply messages.
