Btrfs: fix compiler warning in file.c

Browse source 
While compiling Btrfs, I got following messages:

  CC [M]  fs/btrfs/file.o
fs/btrfs/file.c: In function '__btrfs_buffered_write':
fs/btrfs/file.c:909: warning: 'ret' may be used uninitialized in this function
  CC [M]  fs/btrfs/tree-defrag.o

This patch fixes compiler warning.
