block: fix blktrace timestamps
David Dillow reported broken blktrace timestamps. The reason
is cpu_clock() which is not a global time source.
Fix bkltrace timestamps by using ktime_get() like the networking
code does for packet timestamps. This also removes a whole lot
of complexity from bkltrace.c and shrinks the code by 500 bytes:
text data bss dec hex filename
2888 124 44 3056 bf0 blktrace.o.before
2390 116 44 2550 9f6 blktrace.o.after
