[PATCH v4 03/37] unwind: delete mmap cache in free_libunwind_ui

[Masatake YAMATO]

`free_libunwind_ui' should have responsibility to release all unwind
related resources attached to tcp. Though mmap cache is released outside
of `free_libunwind_ui'. This patch unifies the places where unwind related
resources are released.
