UBI: kill CONFIG_MTD_UBI_BEB_RESERVE 

CONFIG_MTD_UBI_BEB_RESERVE and MIN_RESEVED_PEBS are no longer used,
since the amount of reserved eraseblocks for bad PEB handling is now
derived from 'ubi->bad_peb_limit' (ubi's maximum expected bad
eraseblocks).

If the MTD device admits of bad eraseblocks (e.g. NAND flash), UBI
reserves some amount of physical eraseblocks to handle new bad
eraseblocks. When a physical eraseblock becomes bad, UBI uses these
reserved physical eraseblocks to relocate the bad one. This
configuration option specifies how many physical eraseblocks will be
reserved for bad eraseblock handling (percents of total number of
good physical eraseblocks on this MTD partition). If the underlying
flash does not admit of bad eraseblocks (e.g. NOR flash), this value
is ignored and nothing is reserved. Leave the default value if
unsure.
