[PATCH v2] Documentation/locking/locktypes: minor copy editor fixes

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Minor editorial fixes:
- add some hyphens in multi-word adjectives
- add some periods for consistency
- add "'" for possessive CPU's
- capitalize IRQ when it's an acronym and not part of a function name
