msm: camera: reqmgr: Reset the status for next req if bubble

Browse source 
If req#N in slot idx, and this req meets bubble issue,
then the req#(N+1) in slot (idx+1) may also be applied,
and its status is APPLIED. If req#(N+1) applies failed
after finishing bubble recovery due to some reasons,
but we still can move to next slot since the status of
slot (idx+1) is already APPLIED. This change resets
the status of slot (idx+1) to ADDED if it is APPLIED
during processing error.
