9pfs: fix P9_NOTAG and P9_NOFID macros

Browse source 
The u16 and u32 types don't exist in QEMU common headers. It never broke
build because these two macros aren't use by the current code, but this
is about to change with the future addition of functional tests for 9P.

Also, these should have enclosing parenthesis to be usable in any
syntactical situation.

As suggested by Eric Blake, let's use UINT16_MAX and UINT32_MAX to address
both issues.
