Depends on how fast the magma cooled. There are life forms which can handle up to 122°C and still actively reproduce. Look up hyperthermophiles for more info.

When the magma has cooled enough the rock would be in space or in the upper mars atmosphere at least, not touching anything.

Anything growing on mars surface would burn, only an hypothetical floating microbe could land in this rock after cooling, but would be like expecting a bacteria landing in a bullet, surviving the impact and then sticking to the surface whereas still alive (and much later surviving a second impact against earth after years in outer space). Seems unprobable.
