Summary

With mallocarray() we cannot guarantee that any size larger than
PAGE_SIZE will be contiguous. Switch to use the internal __kmalloc()
implementation which now does provide that guarantee.

Also change the (internal) mallocarray() calls in linux_compat.c to lkpi_mallocarray()
given we are using the LinuxKPI malloc type (M_KMALLOC) there already; better for
consistency.
