hfsplus: fix return value of hfsplus_get_block()
[ Upstream commit 839c3a6a5e1fbc8542d581911b35b2cb5cd29304 ]
Direct writes to empty inodes fail with EIO. The generic direct-io code
is in part to blame (a patch has been submitted as "direct-io: allow
direct writes to empty inodes"), but hfsplus is worse affected than the
other filesystems because the fallback to buffered I/O doesn't happen.
The problem is the return value of hfsplus_get_block() when called with
!create. Change it to be more consistent with the other modules.
