Define new error bit INODE_FLAGS_ERROR to represents invalid inode
flags error.
Symlinks should never have append/immutable flags set.
While checking inodes, if found a symlink with append/immutable
flags, report and record the inode flags error.
This is for lowmem mode.

In lowmem mode with '--repair', check_chunks_and_extents_v2 will fix
accounting in block groups and clear the error bit BG_ACCOUNTING_ERROR.
However, return value of check_btrfs_root() doesn't contain error bits.
If extent tree is on error, lowmem repair always prints error and
returns nonzero value even the filesystem is fine after repair.
Introduce FATAL_ERROR for lowmem mode to represent negative return
values since negative and positive can't be mixed in the bit operations.
Then let check_btrfs_root() return error bits.
