6lowpan: iphc: Fix an off-by-one check of array index
[ Upstream commit 9af417610b6142e826fd1ee8ba7ff3e9a2133a5a ]
The bounds check of id is off-by-one and the comparison should
be >= rather >. Currently the WARN_ON_ONCE check does not stop
the out of range indexing of &ldev->ctx.table[id] so also add
a return path if the bounds are out of range.
Addresses-Coverity: ("Illegal address computation").
Fixes: 5609c185f24d ("6lowpan: iphc: add support for stateful compression")
