load.c: fix `prev_ext_config` clobbering in `require_internal`
The variable `prev_ext_config` is modified by `ext_config_push` between
`setjmp` and `longjmp` calls. Since `ext_config_push` and `ext_config_pop`
are small and likely to be inlined, `prev_ext_config` can be allocated on
a register and get clobbered. Fix by making it `volatile`.
This bug can be observed by adding a check for values greater than 1 in
`th2->ext_config.ractor_safe` after `ext_config_pop` and building with Clang.
