disp: msm: sde: use atomic operator for evt log entries

Browse Source 
To optimize evt log entries, spinlock is been removed and
used atomic operator for curr variable, due to which there
is mismatch of count values between curr and last variable during
xlog dump in kernel. So change the last variable to atomic to
avoid race condition between entries of evt logs.
