UBSAN reported (via LKP)
[ 11.021349][ T1] UBSAN: shift-out-of-bounds in lib/test_scanf.c:275:51
[ 11.022782][ T1] shift exponent 32 is too large for 32-bit type 'unsigned int'
When n_bits == 0, the shift is out of range. Switch code to use GENMASK
to handle this case.
Fixes: 50f530e176ea ("lib: test_scanf: Add tests for sscanf number conversion")

sparse was producing warnings of the form:
sparse: cast truncates bits from constant value (ffff0001 becomes 1)
There is no actual problem here. Using type_min() on an unsigned type
results in an (expected) truncation.
However, there is no need to test an unsigned value against type_min().
The minimum value of an unsigned is obviously 0, and any value cast to
an unsigned type is >= 0, so for unsigneds only type_max() need be tested.
This patch also takes the opportunity to clean up the implementation of
simple_numbers_loop() to use a common pattern for the positive and
negative test.

Adds test_sscanf to test various number conversion cases, as
number conversion was previously broken.
This also tests the simple_strtoxxx() functions exported from
vsprintf.c.
