serial: msm_geni_serial: Perform Abort sequence for cancel failure

Currently driver performing Abort sequence only when we seeing timeout
for Cancel interrupt. When there is a race condition between rx data
coming into rx fifo and a cancel_s_cmd is given. The rx data will end
up consuming the rx dma buffer mapped for cancel command and due to
this geni secondary sequencer will be in active state even after
cancel command.

This changes is to check for geni status after cancel operation. If geni
is active perform abort sequence.
