scsi: fcoe: fix mismatched fcoe_wwn_from_mac declaration

From: Arnd Bergmann <[email protected]>

An old cleanup changed the array size from MAX_ADDR_LEN to unspecified in the declaration, but now gcc-11 warns about this:

drivers/scsi/fcoe/fcoe_ctlr.c:1972:37: error: argument 1 of type ‘unsigned char[32]’ with mismatched bound [-Werror=array-parameter=]
1972 | u64 fcoe_wwn_from_mac(unsigned char mac[MAX_ADDR_LEN],

      |                       ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~
In file included from /git/arm-soc/drivers/scsi/fcoe/fcoe_ctlr.c:33:
include/scsi/libfcoe.h:252:37: note: previously declared as ‘unsigned char[]’
  252 | u64 fcoe_wwn_from_mac(unsigned char mac[], unsigned int, unsigned int);
      |                       ~~~~~~~~~~~~~~^~~~~

Change the type back to what the function definition uses.

Applied to 5.13/scsi-queue, thanks!
