bnxt_en: Fix PTP PPS setting bug
The existing driver logic is always turning on PTP_CLK_REQ_PPS
regardless of the "on" parameter passed to bnxt_ptp_enable().
During shutdown, PTP_CLK_REQ_PPS may be turned off and this
bug will do the opposite and may trigger a PCIe PTM request TLP.
On some systems this can trigger a PCIe AER.
Fix it by properly configuring PTP_CLK_REQ_PPS based on the "on"
parameter.
