[PATCH] Plug memory leak in write_sha1_to_fd()

[PATCH] Plug memory leak in write_sha1_to_fd()

If the object to write was packed, both its uncompressed and compressed
data were leaked.  If the object was not packed, its file was not unmapped.

[jc: I think it still leaks on the write error path of
write_sha1_to_fd(), but that should be fixable in a small separate
patch.]
