erofs: add setlease file operation

Browse source 
Add the setlease file_operation to erofs_file_fops and erofs_dir_fops,
pointing to generic_setlease.  A future patch will change the default
behavior to reject lease attempts with -EINVAL when there is no
setlease file operation defined. Add generic_setlease to retain the
ability to set leases on this filesystem.
