[EXT4 set 9][PATCH3/5]Morecleanups:ext4-remove-extra-is_rdonly-check

[Mingming Cao]

Subject: ext4: remove extra IS_RDONLY() check
From: Dave Hansen <haveblue@xxxxxxxxxx>

ext4_change_inode_journal_flag() is only called from one location:
ext4_ioctl(EXT3_IOC_SETFLAGS).  That ioctl case already has a IS_RDONLY()
call in it so this one is superfluous.
