The function `v9fs_xattrcreate` makes use of the define `XATTR_SIZE_MAX`
to reject attempts of creating xattrs with an invalid size, which is
defined in <linux/limits.h>. On glibc-based systems, this header is
indirectly included via <limits.h>, <bits/posix1_lim.h>,
<bitts/local_lim.h>, but on other platforms this is not guaranteed due
to not being part of the POSIX standard. One examples are systems based
on musl libc, which do not include the <linux/limits.h> indirectly,
which leads to `XATTR_SIZE_MAX` being undefined.
Fix this error by directly include <linux/limits.h>. As the 9P fs code
is being Linux-based either way, we can simply do so without breaking
other platforms. This enables building 9pfs on musl-based systems.
