core: avoid deadlocks caused by single-instance TA

Protect against deadlocks caused by single-instance TAs calling another
single-instance TAs directly or indirectly. When a TA is invoked but
already is busy with another operation the calling thread is suspended
using condvar_wait() until the TA is available again. This is
effectively a lock which can cause a deadlock if several such locks are
used at the same time but in different order.

This patch avoids this problem by only allowing one thread at a time to
set a single-instance TA context busy. If the thread with a
single-instance TA busy in the call stack tries to set an already busy
TA context busy it will return TEE_ERROR_BUSY instead as there is a
recursive loop in how the different TAs has invoked each other.
