[PATCH v4] x86/resctrl: Fix kernel-doc in pseudo_lock.c

[Fabio M. De Francesco]

Add undocumented parameters detected by scripts/kernel-doc.

Signed-off-by: Fabio M. De Francesco <fmdefrancesco@xxxxxxxxx>
---

v3->v4: Restore the description of a parameter to the original text
because it is preferred.
v2->v3: According to a second review by Reinette Chatre, drop many 
unrelated changes that should go in separate patches. Modify also the
patch log.
v1->v2: According to a first review by Reinette Chatre
<reinette.chatre@xxxxxxxxx>, modify the 'Subject' to conform to x86
subsystem, modify a wrong description, and run 'scripts/kernel-doc'
to find out more warnings that 'sparse' didn't notice.
