Pavel Machek 8c14312213 btrfs: fix return value mixup in btrfs_get_extent 
commit 881a3a11c2b858fe9b69ef79ac5ee9978a266dc9 upstream.

btrfs_get_extent() sets variable ret, but out: error path expect error
to be in variable err so the error code is lost.

Fixes: 6bf9e4bd6a27 ("btrfs: inode: Verify inode mode to avoid NULL pointer dereference")
