btrfs: fix error pointer dereference after failure to allocate fs devices
At device_list_add() we allocate a btrfs_fs_devices structure and then
before checking if the allocation failed (pointer is ERR_PTR(-ENOMEM)),
we dereference the error pointer in a memcpy() argument if the feature
BTRFS_FEATURE_INCOMPAT_METADATA_UUID is enabled.
Fix this by checking for an allocation error before trying the memcpy().
Fixes: f7361d8c3fc3 ("btrfs: sipmlify uuid parameters of alloc_fs_devices()")
