ext4: fix INCOMPAT feature codepoint reservation for INLINEDATA
In commit 9b90e5e028 I incorrectly reserved the wrong bit for EXT4_FEATURE_INCOMPAT_INLINEDATA per the discussion on the linux-ext4 list on December 7, 2011. The codepoint 0x2000 should be used for EXT4_FEATURE_INCOMPAT_USE_META_CSUM, so INLINEDATA will be assigned the value 0x8000. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
