disp: msm: sde: add pending ctl recovery mask in sde_kms ...
This change adds pending ctl recovery mask in sde kms
structure to check if there are any ctl paths pending
for recovery and stages only border fill during such
conditions to avoid device crash. Below is the issue
sequence observed during the crash:
1) On one of the ctl path, flush didn't take effect and
flush bits are still pending.
2) It was a NULL flush and last good flush on that
interface has DMA2 pipe staged along with other pipes.
3) Different ctl path re-uses the DMA2 pipe (attached to
ctl path in #1 ) causing wr_ptr timeout followed by
ppdone timeout.
