net: thunderbolt: Fix sparse warnings in tbnet_check_frame() and tbnet_poll()

Browse Source 
Fixes the following warnings when the driver is built with sparse
checks enabled:

main.c:775:47: warning: restricted __le16 degrades to integer
main.c:776:44: warning: restricted __le16 degrades to integer
main.c:876:40: warning: incorrect type in assignment (different base types)
main.c:876:40:    expected restricted __le32 [usertype] frame_size
