Subject: [PATCH  net-next] net: moxa: fix endianness-related issues from 'sparse'

Sparse checker found two endianness-related issues:

.../moxart_ether.c:34:15: warning: incorrect type in assignment (different base types)
.../moxart_ether.c:34:15:    expected unsigned int [usertype]
.../moxart_ether.c:34:15:    got restricted __le32 [usertype]

.../moxart_ether.c:39:16: warning: cast to restricted __le32

Fix them by using __le32 type instead of u32.
