[PATCH 07/24] exfat: add setlease file operation

Add the setlease file_operation to exfat_file_operations and
exfat_dir_operations, 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.
