btrfs: avoid redundant call to get inline ref type at check_committed_ref()
At check_committed_ref() we are calling btrfs_get_extent_inline_ref_type()
twice, once before we check if have an inline extent owner ref (for simple
qgroups) and then once again sometime after that check. This second call
is redundant when we have simple quotas disabled or we found an inline ref
that is not of the owner ref type. So avoid this second call unless we
have simple quotas enabled and found an owner ref, saving a function call
that does inline ref validation again.
