Compiler Attributes: remove unneeded sparse (__CHECKER__) tests
Sparse knows about a few more attributes now, so we can remove
the __CHECKER__ conditions from them (which, in turn, allow us
to move some of them later on to compiler_attributes.h).
* assume_aligned: since sparse's commit ffc860b ("sparse:
ignore __assume_aligned__ attribute"), included in 0.5.1
* error: since sparse's commit 0a04210 ("sparse: Add 'error'
to ignored attributes"), included in 0.5.0
* hotpatch: since sparse's commit 6043210 ("sparse/parse.c:
ignore hotpatch attribute"), included in 0.5.1
* warning: since sparse's commit 977365d ("Avoid "attribute
'warning': unknown attribute" warning"), included in 0.4.2
On top of that, __must_be_array does not need it either because:
* Even ancient versions of sparse do not have a problem
* BUILD_BUG_ON_ZERO() is currently disabled for __CHECKER__
