net/http: consolidate read/write deadline calls into SetDeadline

[davidhsingyuchen]

The updated code seems to be more concise and retains the original
behavior: "SetDeadline sets the read and write deadlines associated
with the connection. It is equivalent to calling both
SetReadDeadline and SetWriteDeadline." (from https://pkg.go.dev/net#Conn)
