8e63083762 xfs: move all scrub input checking to xfs_scrub_validate
There were ad-hoc checks for some scrub types but not others;
mark each scrub type with ... it's type, and use that to validate
the allowed and/or required input fields.

Moving these checks out of xfs_scrub_setup_ag_header makes it
a thin wrapper, so unwrap it in the process.

712d361d59 xfs: calculate correct offset in xfs_scrub_quota_item
It's only used for tracepoints so it's relatively harmless,
but the offset is calculated incorrectly in xfs_scrub_quota_item.

qi_dqperchunk is the nr. of dquots per "chunk" which we have
conveniently *cough* defined to always be 1 FSB.  Therefore
block_offset * qi_dqperchunk == first id in that chunk,
and so offset = id / qi_dqperchunk

id * dqperchunk is ... meaningless.

eda6bc27cc xfs: fix uninitialized variable in xfs_scrub_quota
On the first pass through the while(1) loop, we get to
xfs_scrub_should_terminate() which can test the uninitialized
error variable.
