Subject: [PATCH v3] x86/usercopy: fix kernel-doc function param name

Correct the function parameter name in clean_cache_range() to prevent
kernel-doc warnings:

usercopy_64.c:29: warning: Function parameter or member 'addr' not described in 'clean_cache_range'
usercopy_64.c:29: warning: Excess function parameter 'vaddr' description in 'clean_cache_range'
