fbarray: fix destruction
Currently, when fbarray is destroyed, the fbarray structure is not
zeroed out, which leads to stale data being there and confusing
secondary process init in legacy mem mode. Fix it by always
memsetting the fbarray to zero when destroying it.
Fixes: 5b61c62cfd76 ("fbarray: add internal tailq for mapped areas")
