perf symbols: No need to check if sym->name is NULL
As it is an array, so will always evaluate to 'true', as reported by

builtin-sched.c:2070:19: error: address of array 'sym->name' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]

~~ ~~~~~^~~~
1 warning generated.
So just ditch all those useless checks.
