[PATCH 06/22] loongarch: mm: use mm_is_kernel() in switch_mm_irqs_off()

[Kevin Brodsky]

The new MMF_KERNEL flag identifies kernel-owned mm's. Checking the
flag with mm_is_kernel() is preferred over comparing directly
against &init_mm.

No functional change, as only init_mm has MMF_KERNEL set for now.
