[PATCH v2 kvmtool 02/10] bitops.h: Include wordsize.h to provide the __WORDSIZE define

[Alexandru Elisei]

Trying to build a source file which included bitops.h, but didn't also
bring in the definition for __WORDSIZE (by including limits.h, for example)
would result in the following error:

include/linux/bitops.h:8:23: error: ‘__WORDSIZE’ undeclared (first use in this function)
    8 | #define BITS_PER_LONG __WORDSIZE
      |                       ^~~~~~~~~~

The symbol is defined in the bits/wordsize.h header file, include it.
