core: fix data abort during ftrace

With commit c10e3fa93d24 ("core: fix race in handling TA panic") the
resources of a panicked TAs are released as early as possible, including
the user space mapped ftrace buffer. However, the pointer to the ftrace
buffer is stored in the ts_session for quick and easy access. The ftrace
buffer is always retrieved with get_fbuf() that already have a few other
checks to see if the buffer is currently available. So add a check to
see that the TA hasn't panicked also.
