Subject: [RFC PATCH 2/3] fs: remove duplicate ifdefs

when a ifdef is used in the below manner, second one could be considered as
duplicate.

ifdef DEFINE_A
..code block...
ifdef DEFINE_A
..code block...
endif
..code block...
endif

There are few places in fs code where above pattern was seen.
No functional change is intended here. It only aims to improve code
readability.

The xfs part seems fine to me bcause I think some bot already
complained about this...

Can you please post the xfs changes as a separate patch along with Darrick's
RVB tag? This will make it easy for me to apply the resulting patch to the XFS
tree.
