[PATCH] prio_tree.c: quiet sparse noise

prio_tree.c: quiet sparse noise

The function prio_tree_init is called during start_kernel. Since it
is an __init function it is not exposed as an exported symbol.
A sparse build produces the following warning because of this:

warning: symbol 'prio_tree_init' was not declared. Should it be static?

Quiet the warning by declaring the function as an extern before
it's definition.
