When lnet_text_buf data structure was transform from typedef
to struct the *_t which is typical of typedef was not drop.
This patch removes the *_t to be consistent.

To: Greg Kroah-Hartman, devel, Andreas Dilger, Oleg Dorkin
Cc: Linux Kernel Mailing List, Lustre Development List, James Simmons
Doing if (rc != 0) or if (rc == 0) is bad form. This patch corrects
the LNet code to behavior according to kernel coding standards.
