IB/uverbs: Fix an potential error pointer dereference
smatch reports the warning below:
drivers/infiniband/core/uverbs_std_types_counters.c:110
ib_uverbs_handler_UVERBS_METHOD_COUNTERS_READ() error: 'uattr'
dereferencing possible ERR_PTR()
The return value of uattr maybe ERR_PTR(-ENOENT), fix this by checking
the value of uattr before using it.
