[PATCH] xfs_repair: fix record_allocation list manipulation

clang found this one too as a "Dead assignment"

Unless my pointer-fu is totally messed up, this function
was never actually updating the list head.

This would mean that the later free_allocations() calls in
incore_ext_teardown() and free_rt_dup_extent_tree() don't
actually free more than one item, and therefore leak memory.
