[PATCH] HID: usbhid: Use pr_<level> and remove unnecessary OOM messages

[Joe Perches <joe@perches.com>]

Use a more common logging style and remove the unnecessary
OOM messages as there is default dump_stack when OOM.

Miscellanea:

o Hoist an assignment in an if
o Realign arguments
o Realign a deeply indented if descendent above a printk
