Pointer mid is being initialized however this value is never
read as mid is assigned an updated value in while statement.
Remove the redundant initialization. At the same time, adjust the
declarations order of variables to keep the "upside-down x-mas tree"
look of them.
Clean up clang warning:
arch/x86/kernel/unwind_orc.c:38:7: warning: Value stored to 'mid' during
its initialization is never read [clang-analyzer-deadcode.DeadStores]
