Uninline find_pid etc set of functions
The find_pid/_vpid/_pid_ns functions are used to find the struct pid by its
id, depending on whic id - global or virtual - is used.
The find_vpid() is a macro that pushes the current->nsproxy->pid_ns on the
stack to call another function - find_pid_ns(). It turned out, that this
dereference together with the push itself cause the kernel text size to
grow too much.
Move all these out-of-line. Together with the previous patch this saves a
bit less that 400 bytes from .text section.
