op_attr_bignum_to_user() lacks a call to memtag_strip_tag() before it
calls vm_check_access_rights(). This results in the memory buffer not
being found and the function returning TEE_ERROR_ACCESS_DENIED.
Test case: xtest pkcs11_1019 on QEMUv8, build command:
make CFG_PKCS11_TA=y CFG_USER_TA_TARGET_pkcs11=ta_arm64 MEMTAG=y run
Fixes: ef142203a36b ("core: syscalls: strip tags from user space pointers")
