ptp: ocp: Fix typo using index 1 instead of i in SMA initialization loop

[ Upstream commit a767957e7a83f9e742be196aa52a48de8ac5a7e4 ]

In ptp_ocp_sma_fb_init(), the code mistakenly used bp->sma[1]
instead of bp->sma[i] inside a for-loop, which caused only SMA[1]
to have its DIRECTION_CAN_CHANGE capability cleared. This led to
inconsistent capability flags across SMA pins.
