Jonas Jelonek 33d35975cb net: pse-pd: fix sign on -ENOENT check in of_load_pse_pis() 
of_count_phandle_with_args() returns the count on success and a negative
errno on failure, including -ENOENT when the "pairsets" property is
absent. The existing comparison in of_load_pse_pis() checks against
ENOENT (positive 2) instead of -ENOENT, so the branch is taken for any
error return: legitimate DTs that omit "pairsets" trigger a spurious
"wrong number of pairsets" error and probe fails with -EINVAL.

Compare against -ENOENT so a missing "pairsets" property is correctly
treated as "this PI has no pairsets, continue".
