Marco Elver 6e530e2e31 debugfs: Make debugfs_cancellation a context lock struct ...

When compiling include/linux/debugfs.h with CONTEXT_ANALYSIS enabled, we
can see this error:

./include/linux/debugfs.h:239:17: error: use of undeclared identifier 'cancellation'
  239 | void __acquires(cancellation)

Move the __acquires(..) attribute after the declaration, so that the
compiler can see the cancellation function argument, as well as making
struct debugfs_cancellation a real context lock to benefit from Clang's
context analysis.

This change is a preparatory change to allow enabling context analysis
in subsystems that include the above header.
