IB/qib: fixup indentation in qib_ib_rcv()

Commit af061a6 add some code in qib_ib_rcv() which
trigger a warning from coccicheck (coccinelle/spatch):

$ make C=2 CHECK=scripts/coccicheck drivers/infiniband/hw/qib/

  CHECK   drivers/infiniband/hw/qib/qib_verbs.c
drivers/infiniband/hw/qib/qib_verbs.c:679:5-32: code aligned with following code on line 681
  CC [M]  drivers/infiniband/hw/qib/qib_verbs.o

In fact, according to similar code in qib_kreceive(),
qib_ib_rcv() code is correct but improperly indented.

This patch fix indentation for the misaligned portion.
