[PATCH] net: smc91x: Remove accidentally introduced casts

[Geert Uytterhoeven <geert@linux-m68k.org>]

arm/lpd270_defconfig:

    drivers/net/ethernet/smsc/smc91x.c: In function 'smc_rcv':
    drivers/net/ethernet/smsc/smc91x.c:490:3: warning: passing argument 5 of 'smc_pxa_dma_insw' from incompatible pointer type [enabled by default]
    drivers/net/ethernet/smsc/smc91x.h:423:1: note: expected 'u_char *' but argument is of type 'u16 *'

Introduced by commit afb3df11f1c8925811a1087f2351b0738a3146a2 ("m68k: Atari
EtherNAT warning fixes").

Remove two casts to fix this:
  - The first cast was in the !CONFIG_ATARI case, so it didn't matter for
    us anyway,
  - The second cast is for a pointer parameter we don't do arithmetic
    operations on, so it's also not needed.
