The function parse_flag expects 16 bit value for flag,
but dis_xqe_drop is a byte. Detected when LTO enabled as:
../drivers/net/cnxk/cnxk_ethdev_devargs.c:166: warning: writing 2 bytes into a
region of size 1 [-Wstringop-overflow=]
166 | *(uint16_t *)extra_args = atoi(value);
../drivers/net/cnxk/cnxk_ethdev_devargs.c: In function
‘cnxk_ethdev_parse_devargs’:
../drivers/net/cnxk/cnxk_ethdev_devargs.c:312:17: note: destination object
‘dis_xqe_drop’ of size 1
312 | uint8_t dis_xqe_drop = 0;
