Subject: [PATCH] i40e: fix dma alloc/free prototypes

From: Arnd Bergmann <arnd@...db.de>

gcc-13 notices a mismatch between the declaration and the definition
for a few functions that apparently used to return a i40e_status_code
instead of an int:

drivers/net/ethernet/intel/i40e/i40e_main.c:129:5: error: conflicting types for 'i40e_allocate_dma_mem_d' due to enum/integer mismatch; have 'int(struct i40e_hw *, struct i40e_dma_mem *, u64,  u32)' {aka 'int(struct i40e_hw *, struct i40e_dma_mem *, long long unsigned int,  unsigned int)'} [-Werror=enum-int-mismatch]

Change the prototypes to match the definition.
