xfs: Remove two dead transaction log reservaion macros
Upstream commit 5b292ae3a951a58e32119d73c7ac8f5bec7395a3
xfs: make use of xfs_calc_buf_res() in xfs_trans.c
Beginning from above commit, neither XFS_ALLOCFREE_LOG_RES() nor
XFS_DIROP_LOG_RES() is used by those routines for calculating
transaction space reservations, so it's safe to remove them now.
Also, with a slightly update for the relevant comments to reflect
the ideas of why those log count numbers should be.
