Subject: [PATCH net] net: enetc: shorten enetc_setup_xdp_prog() error message to fit NETLINK_MAX_FMTMSG_LEN

NETLINK_MAX_FMTMSG_LEN is currently hardcoded to 80, and we provide an
error printf-formatted string having 96 characters including the
terminating \0. Assuming each %d (representing a queue) gets replaced by
a number having at most 2 digits (a reasonable assumption), the final
string is also 96 characters wide, which is too much.

Reduce the verbiage a bit by removing some (partially) redundant words,
which makes the new printf-formatted string be 73 characters wide with
the trailing newline.

Fixes: 800db2d125c2 ("net: enetc: ensure we always have a minimum number of TXQs for stack")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/lkml/202311061336.4dsWMT1h-lkp@intel.com/
