Colin Ian King 51b0fe9e23 mac80211: fix potential overflow when multiplying to u32 integers 
[ Upstream commit 6194f7e6473be78acdc5d03edd116944bdbb2c4e ]

The multiplication of the u32 variables tx_time and estimated_retx is
performed using a 32 bit multiplication and the result is stored in
a u64 result. This has a potential u32 overflow issue, so avoid this
by casting tx_time to a u64 to force a 64 bit multiply.

Addresses-Coverity: ("Unintentional integer overflow")
Fixes: 050ac52cbe1f ("mac80211: code for on-demand Hybrid Wireless Mesh Protocol")
