ceph: don't get the inline data for new creating files
If the 'i_inline_version' is 1, that means the file is just new
created and there shouldn't have any inline data in it, we should
skip retrieving the inline data from MDS.
This also could help reduce possiblity of dead lock issue introduce
by the inline data and Fcr caps.
Gradually we will remove the inline feature from kclient after ceph's
scrub too have support to unline the inline data, currently this
could help reduce the teuthology test failures.
This is possiblly could also fix a bug that for some old clients if
they couldn't explictly uninline the inline data when writing, the
inline version will keep as 1 always. We may always reading non-exist
data from inline data.
