ext4: Remove bogus BUG() check in ext4_bmap()
The code to support journal-less ext4 operation added a BUG to
ext4_bmap() which fired if there was no journal and the
EXT4_STATE_JDATA bit was set in the i_state field. This caused
running the filefrag program (which uses the FIMBAP ioctl) to trigger
a BUG().
The EXT4_STATE_JDATA bit is only used for ext4_bmap(), and it's
harmless for the bit to be set. We could add a check in
__ext4_journalled_writepage() and ext4_journalled_write_end() to only
set the EXT4_STATE_JDATA bit if the journal is present, but that adds
an extra test and jump instruction. It's easier to simply remove the
BUG check.
