gianfar: Fix compiler and sparse warnings

commit fba4ed030cfae7efdb6b79a57b0c5a9d72c9de83 ("gianfar: Add Multiple
Queue Support") introduced the following warnings:

  CHECK   gianfar.c
gianfar.c:333:8: warning: incorrect type in assignment (different address spaces)
gianfar.c:333:8:    expected unsigned int [usertype] *baddr
gianfar.c:333:8:    got unsigned int [noderef] <asn:2>*<noident>
[... 67 lines skipped ...]
gianfar.c:2565:3: warning: incorrect type in argument 1 (different type sizes)
gianfar.c:2565:3:    expected unsigned long const *addr
gianfar.c:2565:3:    got unsigned int *<noident>
  CC      gianfar.o

gianfar.c:2566: warning: passing argument 2 of 'test_bit' from incompatible pointer type
gianfar.c:2585: warning: passing argument 2 of 'set_bit' from incompatible pointer type

Following warnings left unfixed (looks like sparse doesn't like
locks in loops, so __acquires/__releases() doesn't help):

gianfar.c:441:40: warning: context imbalance in 'lock_rx_qs': wrong count at exit
gianfar.c:441:40:    context '<noident>': wanted 0, got 1
gianfar.c:449:40: warning: context imbalance in 'lock_tx_qs': wrong count at exit
gianfar.c:449:40:    context '<noident>': wanted 0, got 1
gianfar.c:458:3: warning: context imbalance in 'unlock_rx_qs': __context__ statement expected different context
gianfar.c:458:3:    context '<noident>': wanted >= 0, got -1
gianfar.c:466:3: warning: context imbalance in 'unlock_tx_qs': __context__ statement expected different context
gianfar.c:466:3:    context '<noident>': wanted >= 0, got -1
