Fixed compiler failures when compiling non debug build

storage/maria/ha_maria.cc:
  Don't use 'trn' variable to avoid warning about not used variable
storage/maria/ma_delete.c:
  Added __attribute__((unused))
storage/maria/ma_key_recover.c:
  Added __attribute__((unused))
  Fixed wrong placement of #endif
storage/maria/ma_key_recover.h:
  Fixed typo
