epic100: fix use after free on rmmod
epic_close() calls epic_rx() and uses dma buffer, but in epic_remove_one()
we already freed the dma buffer. To fix this issue, reorder function calls
like in the .probe function.
BUG: KASAN: use-after-free in epic_rx+0xa6/0x7e0 [epic100]
Call Trace:
epic_rx+0xa6/0x7e0 [epic100]
epic_close+0xec/0x2f0 [epic100]
unregister_netdev+0x18/0x20
epic_remove_one+0xaa/0xf0 [epic100]
