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.
