hardening: drop obsolete UBSAN_SANITIZE_ALL from config fragment
[ Upstream commit 006eac3fe20f03ea70765cb02a823dbb8737ec00 ]
Commit 7a628f818499 ("ubsan: Remove CONFIG_UBSAN_SANITIZE_ALL") removes the
config UBSAN_SANITIZE_ALL, but one reference to that config is left in the
hardening.config fragment.
Drop this reference in hardening.config fragment.
Note that CONFIG_UBSAN is still enabled in the hardening.config fragment,
so the functionality when using this fragment remains the same.
