Marius Schilder 0153e43f7f g: broaden dcrypto mutex safety ...

Holding the mutex just around the dcrypto_call is not enough: dcrypto
instruction memory content might change in presence of multiple calling
tasks.

Switching to broad acquire/release pattern instead.

Note to sub-projects: pair your dcrypto_init(_and_lock) w/ matching dcrypto_unlock

BUG=none
BRANCH=cr50
TEST=tcg_tests pass
