drm/nouveau/bios/power_budget: Move an expression into a macro call parameter in nvbios_power_budget_header()
The address of a data structure member was determined before
a corresponding null pointer check in the implementation of
the function “nvbios_power_budget_header”.
Thus avoid the risk for undefined behaviour by moving the usage
of an expression into a parameter for a macro call in one if branch.
This issue was detected by using the Coccinelle software.
