fs: clear or set FMODE_LSEEK based on llseek function
Pipe-like behaviour on llseek(2) (i.e. unconditionally failing with
-ESPIPE) can be expresses in 3 ways:
1) ->llseek set to NULL in file_operations
2) ->llseek set to no_llseek in file_operations
3) FMODE_LSEEK *not* set in ->f_mode.
Enforce (3) in cases (1) and (2); that will allow to simplify the
checks and eventually get rid of no_llseek boilerplate.
