[XFS] kill xfs_igrow_start and xfs_igrow_finish

Browse Source 
xfs_igrow_start just expands to xfs_zero_eof with two asserts that are
useless in the context of the only caller and some rather confusing
comments.

xfs_igrow_finish is just a few lines of code decorated again with useless
asserts and confusing comments.

Just kill those two and merge them into xfs_setattr.
