perf genelf: Fix error code in jit_write_elf()

Browse Source 
The error code is set to -1 at the beginning of jit_write_elf(), but it is
assigned by jit_add_eh_frame_info() in the middle, hence the following
error can only return the error code of jit_add_eh_frame_info(). Reset
the error code to the default value after being assigned by
jit_add_eh_frame_info().

Fixes: 086f9f3d78 ("perf jit: Generate .eh_frame/.eh_frame_hdr in DSO")
