ipv4: fib_semantics: increment fib_info_cnt after fib_info allocation
[ Upstream commit aeefa1ecfc799b0ea2c4979617f14cecd5cccbfd ] Increment fib_info_cnt in fib_create_info() right after successfuly alllocating fib_info structure, overwise fib_metrics allocation failure leads to fib_info_cnt incorrectly decremented in free_fib_info(), called on error path from fib_create_info().
