ARM: tegra: correctly access file in kernel
1. Tell the kernel the pointers from within the kernel address
space are safe before accessing the file. Save/restore current
process address before/after the file accessing.
2. Use macro IS_ERR to check file opening is successful or not
because filp_open() returns negtive value once error happens.
