Use -1 to make it explict which int variables no longer own socket file

Actually shrink, rather than grow, the poll timeout to match comment.

gpiokey driver implements functional subset of gpiokeys device-tree bindings:
https://www.kernel.org/doc/Documentation/devicetree/bindings/input/gpio-keys.txt
It acts as a virtual keyboard, so keys are visible through kbdmux(4)
Driver maps linux scancodes for most common keys to FreeBSD scancodes and
also extends spec by introducing freebsd,code property to specify
FreeBSD-native scancodes.

This logic was added to the whois() function in r281959, but could easily be
its own routine. In this case, I think the abstraction makes both functions
easier to reason about.
This precedes some Coverity-suggested cleanup.

Coverity really should have figured this out from the exit(3) call at the end
of the routine, but just make it explicit.

detect failures, and get different PCI IDs.
For the former the interface returns an int to signal an error. The ID is
returned at a uintptr_t * argument.
For the latter there is a type argument that allows selecting the ID type.
This only specifies a single type, however a MSI type will be added
to handle the need to find the ID the hardware passes to the ARM GICv3
interrupt controller.
A follow up commit will be made to remove pci_get_rid.

Maybe this case is impossible. Either way, when attempting to "/dev/"-prefix a
non-global device name, check that we do not overrun the f_mntfromname buffer.
In this case, truncating (with strlcpy or similar) would not be useful, since
the f_mntfromname result of getmntpt() is passed directly to open(2) later.

Use size of destination buffer, rather than a constant that may or may not
correspond to the source buffer, to restrict the length of copied strings. In
particular, pr_fname has 16+1 characters but MAXCOMLEN is 18+1.
Use strlcpy instead of strncpy to ensure the result is nul-terminated. This
seems to be what is expected of these fields.
