infiniband: remove redundant assignment to pointer 'rdi'

Colin Ian King · jgunthorpe · commit 042932f7a327 · 2018-03-06T16:00:51.000-07:00
The pointer rdi is being initialized with a value that is never read
and re-assigned immediately after, hence the initialization is redundant
and can be removed.

Cleans up clang warning:
drivers/infiniband/sw/rdmavt/vt.c:94:23: warning: Value stored to 'rdi'
during its initialization is never read
