EX-8245 ptlrpc: always do vmalloc

If we were ever to do an allocation with kmalloc, we could
get non-page aligned memory.  So just use vmalloc directly.

Sadly, this isn't the problem with infiniband.  We never
ask for < 8192, which is the libcfs kmalloc/vmalloc cutoff.

Still, this is a timebomb if we ever changed the libcfs
kmalloc/vmalloc cutoff, so, fix it.
