Subject[PATCH v3 02/25] kcsan: Remove redundant zero-initialization of globals
From
They are implicitly zero-initialized, remove explicit initialization.
It keeps the upcoming additions to kcsan_ctx consistent with the rest.

No functional change intended.

v3:
* Minimize diff by leaving "scoped_accesses" on its own line, which
should also reduce diff of future changes.
