staging: lustre: return +ve for blocked lnet message
returned value of lnet_post_send_locked and
lnet_post_routed_recv_locked are changed to -ve by:
http://review.whamcloud.com/#/c/9369/
this is wrong because callers rely on +ve to identify blocked
message which is not a failure.
To respect linux kernel coding style and not use positive error
code, this patch adds two macros as non-error returned values of
these functions:
LNET_CREDIT_OK has credit for message
LNET_CREDIT_WAIT no credit and message is blocked
both these functions will return these two values instead of 0
and EAGAIN
