Tianjia Zhang bb44477d45 crypto: lib/mpi - Fix unexpected pointer access in mpi_ec_init
[ Upstream commit ba3c5574203034781ac4231acf117da917efcd2a ]

When the mpi_ec_ctx structure is initialized, some fields are not
cleared, causing a crash when referencing the field when the
structure was released. Initially, this issue was ignored because
memory for mpi_ec_ctx is allocated with the __GFP_ZERO flag.
For example, this error will be triggered when calculating the
Za value for SM2 separately.
