  Cc: dev, Jerin Jacob Kollanukkaran, stable

Reproduced with "gcc (GCC) 13.0.0 20220616 (experimental)"

Build error:
In file included from ../drivers/net/qede/qede_debug.c:9:
../drivers/net/qede/qede_debug.c: In function ‘qed_grc_dump_addr_range’:
../drivers/net/qede/base/ecore.h:95:17:
	warning: overflow in conversion from ‘int’ to ‘u8’
	{aka ‘unsigned char’} changes value from ‘(int)vf_id << 8 | 128’
	to ‘128’ [-Woverflow]
   95 |                 ((_value & _name##_MASK) << _name##_SHIFT)
      |                 ^
../drivers/net/qede/qede_debug.c:1907:31:
	note: in expansion of macro ‘FIELD_VALUE’
 1907 |         fid = FIELD_VALUE(PXP_PRETEND_CONCRETE_FID_VFVALID, 1)
      |               ^~~~~~~~~~~

To prevent overflow converting 'fib' to uint16_t,
while updating it also updated 'vf_id' to 16 bit too.
