ext2, dax: set ext2_dax_aops for dax files
Sync syscall to DAX file needs to flush processor cache, but it
currently does not flush to existing DAX files. This is because
'ext2_da_aops' is set to address_space_operations of existing DAX
files, instead of 'ext2_dax_aops', since S_DAX flag is set after
ext2_set_aops() in the open path.
Similar to ext4, change ext2_iget() to initialize i_flags before
ext2_set_aops().
