Mark O'Donovan ae63e84ffd crypto: lib/mpi - avoid null pointer deref in mpi_cmp_ui() ...

[ Upstream commit 9e47a758b70167c9301d2b44d2569f86c7796f2d ]

During NVMeTCP Authentication a controller can trigger a kernel
oops by specifying the 8192 bit Diffie Hellman group and passing
a correctly sized, but zeroed Diffie Hellamn value.
mpi_cmp_ui() was detecting this if the second parameter was 0,
but 1 is passed from dh_is_pubkey_valid(). This causes the null
pointer u->d to be dereferenced towards the end of mpi_cmp_ui()
