fs: add setlease to generic_ro_fops and read-only filesystem directory operations
Add the setlease file_operation to generic_ro_fops, which covers file
operations for several read-only filesystems (BEFS, EFS, ISOFS, QNX4,
QNX6, CRAMFS, FREEVXFS). Also add setlease to the directory
file_operations for these filesystems. 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 these filesystems.
