btrfs-progs: replace errno with %m in cmd_inspect_list_chunks()

Browse source 
The variable @e is only utilized to record the errno from ioctl() call,
and is only for the error message.

We can go with "%m" to replace the usage of variable @e, and remove the
variable shadowing, as later we will declare a local variable @e with a
different type.
