From: Jie Liu <jeff.liu@xxxxxxxxxx>
At xfs_iext_add(), if extent(s) are being appended to the last
page in the indirection array and the new extent(s) don't fit
in the page, the number of extents(erp->er_extcount) in a new
allocated entry should be the minimum value between count and
XFS_LINEAR_EXTS, instead of count.
