mds/MDCache.h: init some members of open_ino_info_t in ctor

Fix for:

CID 1026809 (#1 of 1): Uninitialized scalar field (UNINIT_CTOR)
 uninit_member: Non-static class member want_replica is not
  initialized in this constructor nor in any functions that
  it calls.
 uninit_member: Non-static class member want_xlocked is not
  initialized in this constructor nor in any functions that
  it calls.
 uninit_member: Non-static class member tid is not initialized
  in this constructor nor in any functions that it calls.
 uninit_member: Non-static class member pool is not initialized
  in this constructor nor in any functions that it calls.
