This reverts commit 35aee01f

Commit 35aee01f ("wifi: wilc1000: set atomic flag on kmemdup in srcu
critical section") was preparatory to the SRCU to RCU conversion done by
commit f236464f ("wifi: wilc1000: convert list management to RCU").
This conversion brought issues and so has been reverted, so the atomic flag
is not needed anymore.
