static_call: Fix static_call_text_reserved() vs __init

Browse source

[ Upstream commit 2bee6d16e4 ]

It turns out that static_call_text_reserved() was reporting __init
text as being reserved past the time when the __init text was freed
and re-used.

This is mostly harmless and will at worst result in refusing a kprobe.
