Subject: IB/core: Expose ib_ucontext from a given ib_uverbs_file
Patch-mainline: v4.19-rc1
Git-commit: 7dc08dcfc8c86cb4457e383734ff6844ddaff876
References: bsc#1103992 FATE#326009

Drivers that use the IOCTL API may have the ib_uverbs_file and need a
way to get the related ib_ucontext from it, this is enabled by this
patch.

Downstream patches from this series will use it.
