kdb: Get rid of redundant kdb_curr_task()

Browse Source 
Commit cf8e865810 ("arch: Remove Itanium (IA-64) architecture")
removed the only definition of macro _TIF_MCA_INIT, so kdb_curr_task()
is actually the same as curr_task() now and becomes redundant.

Let's remove the definition of kdb_curr_task() and replace remaining
calls with curr_task().
