* Fix a null pointer dereference when mbedtls_mpi_exp_mod() was called with
A=0 represented with 0 limbs. Up to and including Mbed TLS 2.26, this bug
could not be triggered by code that constructed A with one of the
mbedtls_mpi_read_xxx functions (including in particular TLS code) since
those always built an mpi object with at least one limb.
Credit to OSS-Fuzz. Fixes #4641.
