IB/ipath: Fix incorrect use of sizeof on msg buffer (function argument)
Inside a function declared as
void foo(char bar[512])
the value of sizeof bar is the size of a pointer, not 512. So avoid
constructions like this by passing the size explicitly.
Also reduce the size of the buffer to 128 bytes (512 was overly generous).
