ext4: add EXT4_FLAGS_EMERGENCY_RO bit
EXT4_FLAGS_EMERGENCY_RO Indicates that the current file system has become
read-only due to some error. Compared to SB_RDONLY, setting it does not
require a lock because we won't clear it, which avoids over-coupling with
vfs freeze. Also, add a helper function ext4_emergency_ro() to check if
the bit is set.
