kasan: fix array-bounds warnings in tests
GCC's -Warray-bounds option detects out-of-bounds accesses to
statically-sized allocations in krealloc out-of-bounds tests.
Use OPTIMIZER_HIDE_VAR to suppress the warning.
Also change kmalloc_memmove_invalid_size to use OPTIMIZER_HIDE_VAR
instead of a volatile variable.
