btrfs: fix lost return value due to variable shadowing
commit 1932b7be973b554ffe20a5bba6ffaed6fa995cdc upstream.
A block-local variable stores error code but btrfs_get_blocks_direct may
not return it in the end as there's a ret defined in the function scope.
Fixes: d187663ef24c ("Btrfs: lock extents as we map them in DIO")
