arm64: vdso: defer shifting of nanosecond component of timespec
Shifting the nanosecond component of the computed timespec early can lead to sub-ns inaccuracies when using the truncated value as input to further arithmetic for things like conversions to monotonic time. This patch defers the timespec shifting until after the final value has been computed.
