[PATCH 22/60] xfs: move xfs_trans_reservations to xfs_trans.h

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

struct xfs_trans_reservations is the only non kernel-only definition
in xfs_mount.h. Move it to xfs_trans.h so that we no longer need
xfs_mount.h in the userspace code. Most places that include
xfs_mount.h already include xfs_trans.h and xfs_trans.h is shared
with userspace, so there are no major concerns about moving this
structure there.

While in xfs-mount.h, remove the remaining two #defines that are
defined for userspace - the kernel code has a separate definition of
the macros so this is purely userspace code. This allows us to
remove the __KERNEL__ switches from xfs_mount.h entirely.
