[PATCH] lib/test_stackinit: move a local outside the switch statement

From: glider
Date: Tue Feb 18 2020 - 04:48:22 EST


Right now CONFIG_INIT_STACK_ALL is unable to initialize locals declared
in switch statements, see http://llvm.org/PR44916.
Move the variable declaration outside the switch in lib/test_stackinit.c
to prevent potential test failures until this is sorted out.
