[PATCH scripts] scripts/sorttable: Fix resource leak in parse_symbols()

[Dheeraj Reddy Jonnalagadda]

Fix a resource leak in parse_symbols() where the file pointer fp
was not closed if add_field() returned an error. This caused an
open file descriptor to remain unclosed. Ensure that fp is properly
closed before returning an error.

Fixes: ef378c3b8233 ("scripts/sorttable: Zero out weak functions in mcount_loc table")
