[PATCH 52/67] xfs: remove rt-wrappers from xfs_format.h

Darrick J. Wong

From: Christoph Hellwig <hch@lst.de>

Source kernel commit: 3abfe6c2759e2e3000b13f8ce8a1a325e80987a1

xfs_format.h has a bunch odd wrappers for helper functions and mount
structure access using RT* prefixes. Replace them with their open coded
versions (for those that weren't entirely unused) and remove the wrappers.
