i2c: qcom-geni: use cancel command before abort on transfer timeout
The GENI I2C driver currently invokes geni_se_abort_m_cmd() directly when
a transfer times out. However, the GENI hardware command cancellation
flow requires a cancel command to be issued first. An abort should only
be used as a fallback when the cancel operation itself fails to complete.
Introduce a dedicated cancel_done completion that is signaled when
M_CMD_CANCEL_EN is received. The timeout recovery path waits for cancel
completion and escalates to geni_i2c_abort_xfer() only if the cancel
command does not complete within the expected time.
