Sagar Bijwe 0f1710d878 wpa_supplicant: Fix SAE test-case failure on mbedtls version udpate
Problem:
mbedtls_ctr_drbg_context was initialized in crypto_ec_point_mul. This
was okay in releases before 2.16.4 as entropy_len used to get set to
MBEDTLS_CTR_DRBG_ENTROPY_LEN in function mbedtls_ctr_drbg_seed. The
function is now changed to set the length to
MBEDTLS_CTR_DRBG_ENTROPY_LEN if previous length is 0 and hence the bug.

Solution:
Initialize mbedtls_ctr_drbg_context in crypto_ec_point_mul.
