Description: MDS or OSS nodes crash due to stack overflow
Details    : Code changes in 1.8.0 increased the stack usage of some functions.
             In some cases, in conjunction with device drivers that use a lot
             of stack the MDS (or possibly OSS) service threads could overflow
             the stack.  One change which was identified to consume additional
             stack has been reworked to avoid the extra stack usage.

1) set as "inline" for such large function ("obd_fail_check()") is not suitable,
   replaced with normal function "__obd_fail_check_set()".
2) atomic operations for obd_fail_count (replace "static count" in obd_fail_check).
3) use "test_and_set_bit()" for "OBD_FAILED/OBD_FAIL_ONCE" check and set to avoid
   unexpected racing condition between multi-thread ops.
4) some cleanup for OBD_FAIL_XXX macro.
