Subject: [PATCH] simplify conversions from slice to array (#5818)

Go 1.17 introduced an expression for convertion from slice to array, so
codes can be simplified.
Ref:
https://tip.golang.org/ref/spec#Conversions_from_slice_to_array_or_array_pointer
> Converting a slice to an array yields an array containing the elements
of the underlying array of the slice.
