Filipe Manana 29d47d00e0 Btrfs: fix inode cache block reserve leak on failure to allocate data space 
If we failed to allocate the data extent(s) for the inode space cache, we
were bailing out without releasing the previously reserved metadata. This
was triggering the following warnings when unmounting a filesystem:

  $ cat -n fs/btrfs/inode.c
  (...)
  9268  void btrfs_destroy_inode(struct inode *inode)
  9269  {
  (...)
  9276          WARN_ON(BTRFS_I(inode)->block_rsv.reserved);
  9277          WARN_ON(BTRFS_I(inode)->block_rsv.size);
  (...)
  9281          WARN_ON(BTRFS_I(inode)->csum_bytes);
  9282          WARN_ON(BTRFS_I(inode)->defrag_bytes);
  (...)

Several fstests test cases triggered this often, such as generic/083,
generic/102, generic/172, generic/269 and generic/300 at least, producing
stack traces like the following in dmesg/syslog:
