perf events: Fix mmap offset determination
Fix buggy-looking code which unnecessarily adjusts the file offset
fields read from /proc/*/maps.
This may have gone unnoticed since the offset is usually 0 (and the
logic in util/symbol.c may work incorrectly for other offset values).
Commiter note:
This fixes a bug introduced in 4af8b35, there is no need to shift pgoff
twice, the show_map_vma routine in fs/proc/task_mmu.c already converts
it from the number of pages to the size in bytes, and that is what
appears in /proc/PID/map.
