Natalia Petrova 8b152e9150 trace_events_hist: add check for return value of 'create_hist_field' 
Function 'create_hist_field' is called recursively at
trace_events_hist.c:1954 and can return NULL-value that's why we have
to check it to avoid null pointer dereference.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
