mm/shmem: remove dead code can not be satisfied by "(CONFIG_SHMEM)&&(!(CONFIG_SHMEM))"
The value of “.fs_flags” in line 4608 is a dead code which will never be implemented,because its conditions of line 47 "#ifdef CONFIG_SHMEM" and line 4607 are mutually exclusive. It is recommended to delete redundant code.
