BFS error when installing several times with Installer

[korli]

CachedNode::Allocate() returns B_ERROR on a testcase:

• Run Installer with two twin haiku hd images in QEmu.
• Install boot partition on the other, several times if needed.
• An alert should appears telling "Error copying ??? ??? : General system

error".

• The serial log displays "bfs: Allocate:330: General system error", which is

the last line in CachedNode::Allocate().

• The good news is Haiku doesn't crash at all, it just runs normally after this

error.

ps tells memory is used 42% QEmu uses 282Mo when configured for a 256Mo VM.

identified an error code path : =>bfs_create_symlink(void *_ns, void *_directory, const char *name, const char *path, int mode):841 =>Inode::Create(Transaction &transaction, Inode *parent, const char *name, int32 mode,

I also commit changes to trace this error code path

Seems fixed with recent kernel changes
