net: wan: sdla: Fix cast from pointer to integer of different size

[ Upstream commit 00c0688cecadbf7ac2f5b4cdb36d912a2d3f0cca ]

Since net_device.mem_start is unsigned long, it should not be cast to
int right before casting to pointer.  This fixes warning (compile
testing on alpha architecture):

    drivers/net/wan/sdla.c: In function ‘sdla_transmit’:
    drivers/net/wan/sdla.c:711:13: warning:
        cast to pointer from integer of different size [-Wint-to-pointer-cast]
