bpf: fix bpf expression parsing regression in GAS
As a result of a switch instead of an if, as would issue non-specific
error messages when it encountered an operand it could not parse in bpf.
This patch fixes that regression and adds a test to prevent it from
reoccurring.
Tested for bpf-unknown-none on x86_64-redhat-linux.
gas/ChangeLog:
* config/tc-bpf.c (parse_expression): Change switch to if so that error
* condition is handled.
* testsuite/gas/bpf/bpf.exp: Invoke new test.
