The `klp_enable_patch()` function is the main entrypoint to the livepatch
subsystem, and is invoked by a KLP module from the module_init callback
when it is ready to be enabled.  The livepatch documentation specifies that
`klp_enable_patch()` should be invoked from the `module_init()` callback,
but does not actually link the user to the function's kerneldoc comment.

This simple change therefore adds a kernel-doc directive to link the
`klp_enable_patch()` function's kerneldoc comment in the livepatch
documentation page. With this, kernel/livepatch/core.c no longer comes up
as a file containing an unused doc with
`scripts/ kernel/livepatch`
