pinctl: ti: iodelay: fix error checking on pinctrl_count_index_with_args call

Browse Source 
The call to pinctrl_count_index_with_args checks for a -EINVAL return
however this function calls pinctrl_get_list_and_count and this can
return -ENOENT. Rather than check for a specific error, fix this by
checking for any error return to catch the -ENOENT case.

Addresses-Coverity: ("Improper use of negative")
Fixes: 003910ebc8 ("pinctrl: Introduce TI IOdelay configuration driver")
