Fix race conditions in ndo_get_stats64 by implementing a state variable
check, and remove unnecessary firmware stats fetch which is currently
unnecessary

Changes:
V3:
  - Added warn log that happened due to rcu_read_lock in commit message

V2: https://lore.kernel.org/all/20241216075842.2394606-1-srasheed@marvell.com/
  - Changed sync mechanism to fix race conditions from using an atomic
    set_bit ops to a much simpler synchronize_net()
