[PATCH] Revert "printf: Compile the kunit test with DISABLE_BRANCH_PROFILING DISABLE_BRANCH_PROFILING"

[Petr Mladek]

This reverts commit 8901ac9d2c7eb8ed7ae5e749bf13ecb3b6062488.

The commit 94bfc7f3b0c7 ("err.h: use __always_inline on all error pointer
helpers") fixes the problem with a dead code elimination by always inlining
IS_ERR() function. It prevents the related linker failures as well.

The workaround with disabling branch profiling is not longer necessary.
