rust: Add -fno-isolate-erroneous-paths-dereference to bindgen_skip_c_flags

[ Upstream commit fe4b3a34e9a9654d98d274218dac0270779db0ae ]

It's used to work around an objtool issue since commit abb2a5572264
("LoongArch: Add cflag -fno-isolate-erroneous-paths-dereference"), but
it's then passed to bindgen and cause an error because Clang does not
have this option.

Fixes: abb2a5572264 ("LoongArch: Add cflag -fno-isolate-erroneous-paths-dereference")
