IPC: blake3 x86 asm: fix placement of .size directives 

The .size directive used by the SET_SIZE C macro uses the special
dot symbol to calculate the size of a function. The dot symbol
refers to the current address, so for the calculation to be
meaningful the SET_SIZE macro must be placed immediately after the
end of the function the size is calculated for.
