shelve: remove useless and incorrect code paths for file access

This patch removes code paths in "shelvedfile.opener()", because:

    - explicit "vfs.mkdir()" invocation is useless

      "vfs.__call__()" for modes other than "read" creates parent
      directory of target file automatically by "util.ensuredirs()".

    - mode checking in "except IOError" code path is useless

      ENOENT occurs only for "read" mode, because target file is
      created forcibly for other modes.

    - there is no explicit "return" statement in the code path for
      "except IOError" if "mode[0] in 'wa'"

      this is incorrect, because None may be returnd unexpectedly,
      even though it seems the EEXIST case in the directory creation
      race for ".hg/shelved" and is very rare.

      this directory creation race is also treated in
      "util.ensuredirs()".
