net/bnxt: fix setting link speed
bnxt PMD uses the macro BNXT_SUPPORTED_SPEEDS to validate
the user requested speed. But this has all the speed values
supported by the PMD and is not chip specific.
The check against this macro returns success when the user
tries set the speed to 100G on a port even if the chip does
not support 100G speed.
Fixed it to use bnxt_get_speed_capabilities() to check the
supported speeds by the chip.
