[PATCH] receive-pack: use FLEX_ALLOC_MEM in queue_command()

Use the macro FLEX_ALLOC_MEM instead of open-coding it.  This shortens
and simplifies the code a bit.

Thanks, looks good (I obviously missed a few opportunities for
conversion during the initial introduction of FLEX_ALLOC simply by not
noticing; I don't think there is any more reason that this one was not
converted).
