Fix kernel oops when CONFIG_DEBUG_ATOMIC_SLEEP is enabled.
Removed oplock_break_received flag which was added to achieve synchronization between oplock handler and open handler by earlier commit. It is not needed because there is an existing lock open_file_lock to achieve the same. find_readable_file takes open_file_lock and then traverses the openFileList. Similarly, cifs_oplock_break while closing the deferred handle (i.e cifsFileInfo_put) takes open_file_lock and then sends close to the server. Added comments for better readability.
