There is no point to continuing assignment after memory allocation
failed, rather throw error immediately.

Fixes vb2_vmalloc_get_userptr() to ioremap correct area.
Since the current code does ioremap the page address, if the offset > 0,
it does not do ioremap the last page and results in kernel panic.
This fixes to pass the size + offset to ioremap so that ioremap
can map correct area. Also, this uses __pfn_to_phys() to get the physical
address of given PFN.

This directory contains the videobuf2 framework, so name the
directory accordingly.
The name 'videobuf' typically refers to the old and deprecated
videobuf version 1 framework so that was confusing.
