MDCAHCE: fix bad setting of MDCACHE_TRUST_ATTRS when refresh attrs
Two WRITEs of the same file, the second WRITE returns bad attrs as the first.
Thread one thread two
mdcache_write2()
atomic_clear MDCACHE_TRUST_ATTRS
mdcache_getattrs()
wrlock(&entry->attr_lock)
mdcache_refresh_attrs()
obj_ops.getattrs() mdcache_write2()
atomic_clear MDCACHE_TRUST_ATTRS
mdc_fixup_md()
set MDCACHE_TRUST_ATTRS
unlock(&entry->attr_lock)
mdcache_getattrs()
tusts the attrs in MDCACHE
This patch records the count of atomic_clear(MDCACHE_TRUST_ATTRS) during
attrs refreshing, sets MDCACHE_TRUST_ATTRS only if the count is zero
after attrs is refreshed.
