Use kmalloc() to allocate fdmem if possible.

vmalloc() is used as a fallback solution for fdmem allocation.  A new
helper function __free_fdtable() is introduced to reduce the lines of
code.

A potential bug, vfree() a memory allocated by kmalloc(), is fixed.

'make htmldocs' has a fatal error when processing libata.xml, as seen

produce an <informalexample> block without a beginning <para>, but
there is an ending </para> generated, which throws things out of kilter.

I don't even know where (what program) this is happening in.
I searched in docproc and xmlto and in some XML stylesheets without
finding anything.  If anyone can give me pointers about this, please do.
Until this is fixed, let's just spell "Example" as "Sample"
