hannken b7bd248623 When truncating a file purge the fat cache after setting the new size
and after all io but before actually updating the cluster chain.

Both uvm_vnp_zerorange() and vtruncbuf() call get/putpages -> bmap -> pcbmap
and here the fat cache gets updated with information no longer valid after
truncation.
