bnxt_en: Fix a possible memory leak in bnxt_ptp_init

Browse Source 
[ Upstream commit deb8eb39164382f1f67ef8e8af9176baf5e10f2d ]

In bnxt_ptp_init(), when ptp_clock_register() fails, the driver is
not freeing the memory allocated for ptp_info->pin_config.  Fix it
to unconditionally free ptp_info->pin_config in bnxt_ptp_free().

Fixes: caf3eedbcd ("bnxt_en: 1PPS support for 5750X family chips")
