kdump: use is_kdump_kernel() in sba_init()

Browse Source 
o Make use of is_kdump_kernel() rather than checking elfcorehdr_addr directly.

o Remove CONFIG_CRASH_DUMP as is_kdump_kernel() is safe to call anywhere

o Remove CONFIG_PROC_FS as it is bogus, the check
  should occur regardless of if CONFIG_PROC_FS is set or not.
